General Instructions and Information ........................................... 4-5
The seller shall not be liable for any injury, loss or damage, direct or consequential, arising
from the use or inability to use the product. Prior to use, the purchaser shall determine the
suitability of the product for the intended use and assume all risks and liabilities.
The obligation of Speedotron Corporation is limited to repair or replacement only, and no one
is authorized to assume any obligation not in accordance with the above.
Do not attempt to make repairs to your Speedotron equipment. All electronic flash systems
operate on high voltage and high power. There is a high risk of severe electrical shock when
opening a power supply or light unit. Leave service to qualified and authorized electrical service
personnel. Authorized service personnel are familiar with the procedure to fully discharge a live

2-year u.s. limited warranty
Speedotron’s 2-Year U.S. Limited Warranty
Although Speedotron Black Line power supplies vary in power
and features, they all operate under the same principles. The
following instructions apply to the entire Black Line series. For
maximum equipment life and for safe, dependable operation of
power supplies, we advise you to follow these general rules.
• Information contained in this manual is applicable to New Speedotron
Equipment at the time of writing. Some information may not be applicable
to older Speedotron equipment.
• Before doing anything with the power supply make sure that the Model
and Power switches are in the off position and the Reset button (circuit
breaker) is fully depressed into its socket.
• Connect light cable(s) to the Light Unit Outlet(s) on the power supply
(with the103, 202VF and 206VF lights, connect the light unit cable to the
light unit before connecting to power supply), selecting the appropriate
outlets for the desired power level. (Refer to the diagrams on the side of
the power supply.)
• To insert, align the light unit plug with the power supply outlet and apply
even pressure while pushing. Make sure that all light unit cables are firmly
seated and you hear or feel the quick release ring click into place or the
lockring of 206 light units is fully threaded.
• Make sure cables are out of pathways or are taped to the floor to prevent
accidentally disconnecting cables from power supply.
• Never connect or disconnect a light unit while the power supply is turned
on. Never insert or remove flash tubes while the light unit is connected to
the power supply. Be sure flash tubes are fully seated into light unit
sockets. (Read instructions in the Light Units section of this manual for
more information on light unit assembly and operation.)
• Always make sure your Model and Power switches are off when
disconnecting or connecting light units. Speedotron power supplies are
equipped with arc-protected outlets. However, as with any electrical
equipment, arc-over (an electrical discharge between two physically
disconnected electrical terminals) is a possibility. When light cables, flash
tubes or power cords are improperly seated, arc-over may occur. Also, if
your light unit or power supply malfunctions, or the power cord or the
internal wiring in the studio is improperly terminated or defective, there is a
chance of arc-over. Severe power supply damage and operator injury may
result if arc-over occurs.
• Plug sync extension into Sync socket and connect other end to PC cord for
camera. These sync extensions have a 1/4” international (phone jack) plug.
• Insure that protective flashtube covers are removed from light units before
turning on model lamps or flashing.
• A slave tripper (Speedotron #23510) may be installed in the Sync socket to
fire the power supply. The 805 features a built-in slave trigger for added
convenience.
• Connect AC power cord into Power Input on power supply. Always use a
three-wire ground power cord and a properly grounded wall outlet with all
4
Speedotron power supplies. Failure to do so may cause the power supply
to intermittently misfire. Do not use a three prong-to-two prong “ground
eliminator” adapter.
• Once the light units are properly assembled and installed, the power cord
is installed and the sync extension is connected, turn the Power switch on.
Do not immediately fire the unit on the first use or when the unit has been
idle for periods over 3 weeks. Allow several minutes for the power
supply’s capacitors to form. Once this procedure has been followed at
these times, subsequent use of the power supply requires no waiting
period.
• Ready/Push to Flash button may be depressed to verify proper system
operation.
• When Power is on, be sure Ready/Push to Flash indicator is illuminated
before switching Power, Combine/Isolate, or Fast/Slow* controls. Do not
move these switches while the unit is recycling.
• Each Black Line power supply's unique features are fully explained in the
next section of this manual.
Never attempt to make repairs to your Speedotron equipment. All
electronic flash systems operate on high voltage and power.
It is very dangerous to open a power supply.
To summarize, set-up should go as follows:
• Make sure power supply is off (both Model and Power switches in the off
position) and unplugged.
• Connect light units to power supply. Inspect all connections, flash tubes
and modeling lights. Set desired ratio.
• Connect sync cable to power supply and camera
• Connect power supply to AC. Turn on power supply and wait for it to reach
full charge.
• Test to see that all light units are flashing and slave triggers (if any) are
functioning.
Power Ratios
Black Line equipment is capable of symmetrical (all light units receiving the
same amount of light) or asymmetrical (ratioed) power distribution. Controlling
distribution is as easy as flipping a switch.
Each power supply is divided into three channels with different levels of
power, except for the 405 (which has two). These channels may may be joined
for even (symmetrical) output to all outlets or separated for unequal
(asymmetrical) output to a set of outlets in one or more channels. Power
distribution charts are provided in the next section of this manual and on the
side of each power supply.
When we refer to ratioing, we are describing the levels of power output
from the power supply to the light units only. These power output ratios do not
mean that the light falling on the subject will be at that same ratio. This will only
occur if the light units are the same and have the same flash tube, reflector,
cable length, light control accessories, are at the same distance to the subject,
and there is no overlap of lighting on the subject, etc. Power output ratios are
only offered as a guide to help you determine your lighting arrangements.
*Not available on 405/805 power supplies.

2403CX LV Description of Controls
1) Power — turns power supply on and off.
2) Model Light — turns model lamps on and off.
3) 800Ws Isolate/Combine — when in isolate, this switch isolates the
800Ws channel from the 1200Ws channel and provides two Light Unit
Outlets per channel. When in combine, will provide 2400Ws among 4 Light
Unit Outlets.
4) 400Ws Isolate/Combine — when in isolate, this switch isolates the
400Ws channel from the 1200Ws channel and provides two Light Unit
Outlets per channel. When in combine, will provide 1600Ws among four
Light Unit Outlets. (With both 800Ws and the 400Ws switches in combine,
2400Ws is available through any of the six Light Unit Outlets, divided equally.
See diagrams on the side of the power supply and page 15 for detailed
examples of the ratio system).
5) Variable Power Control — simultaneously controls power of all three
channels, with ten positions down to -3 stops (1/8 power). Power ratios
among the light units are unaffected since there is a proportional change in all
power levels.
6) Recycle Rate — controls recycle rate.
7)Charge/Ready/Push to Flash — red Charge light is illuminated whenever
the power supply is charging up or down to the selected level. Green Ready
light is lit whenever the 2403CX LV is fully charged to the selected power
level. An audible beep will sound when the green Ready light comes on.
Push to Flash button is for manual triggering of flash for testing or open flash
application.

Set Isolate/Combine switches and Variable Power Control as desired.
See the side of the power supply for various ratio combinations. With the
Variable Power Control in the Full position, power is determined by the
choice of outlets and position of ratio switches. The Variable Power Control
simultaneously changes the power level of all three channels. Rotating the
Variable Power Control immediately adjusts the power level of the 2403CX
LV. The power supply does not need to be discharged between settings.
Turn Power Switch on. The red Charge indicator will illuminate. After a
few seconds, the green Ready indicator will illuminate and an audible beep
will sound. (The beep will not be produced when a very small power change is
made. Changing the power level by a third f-stop or so is done very rapidly
with the 2403CX LV; the Ready light will usually remain on) The power supply
is now charged to the selected level, and ready to fire. Do not immediately
fire the unit on the first use or when the unit has been idle for periods over 3
weeks. Allow several minutes for the power supply’s capacitors to form.
Push to Flash button may be depressed to verify proper system operation.
When Power is on, be sure Ready indicator is illuminated before switching
Power or Fast/Slow. Do not move these switches while the unit is recycling.
When disassembling the system, turn Power switch to the off position.
The 2403CX LV power supply will automatically discharge its storage
capacitors. Do not push the Push to Flash switch before turning power

4803CX LV Operating Instructions
The following sequence of operation should be utilized for maximum
life and dependability of the 4803CX LV power supply.
Make sure that the Model and Power switches are in the off position and
the Reset button (circuit breaker) is fully depressed into its socket.
Connect light unit cable(s) to the Light Unit Outlet(s) on the power supply,
selecting the appropriate outlet(s) for the desired power level. Any Black Line
Universal Light Unit may be attached to the left and center Light Unit
Outlets. Only Model 206VF light units may be attached to the right Light Unit
Outlets. (See Universal Light Units section of this manual for information on
assembling light units.)
4803CX LV Description of Controls
1) Power — turns power supply on and off.
2) Model Light — turns model lamps on and off.
3) Isolate/Combine (left switch) — when in isolate, the two left Light Unit
Outlets provide 800 and 1600Ws, respectively. When in combine, one left
Light Unit Outlet provides 2400Ws or with two light units installed, each
provides 1200Ws. The two middle Light Unit Outlets provide 1200Ws each
when two light units are installed, or 2400Ws when one is used.
4) Isolate/Combine for Model 206VF Light Units (right switch) — when in
isolate, each special 206VF Light Unit Outlet provides 2400Ws, whether one
or two 206VF light units are attached. When in combine, a single Light Unit
Outlet provides 4800Ws. With two 206VF light units attached, each Light
Unit Outlet provides 2400Ws. Use of both standard and special outlets can
produce numerous additional lighting possibilities. (See diagram on page 20)
5) Variable Power Control — simultaneously controls power of all three
channels, with ten positions down to -3 stops (1/8 power). Power ratios
among the light units are unaffected since there is a proportional change in all
power levels.
6) Recycle Rate — controls recycle rate.
7) Charge/Ready/Push to Flash — red Charge light is illuminated whenever
the power supply is charging up or down to the selected level. Green Ready
light is lit whenever the 4803CX LV is fully charged to the selected power
level. An audible beep will sound when the green Ready light comes on.
Push to Flash button is for manual triggering of flash for testing or open flash
application.
18
Set Isolate/Combine switches and Variable Power Control as desired.
See the side of the power supply for various ratio combinations. With the
Variable Power Control in the full position, power is determined by the
choice of outlets and position of ratio switches. The Variable Power Control
simultaneously changes power of all three channels. Rotating the Variable
Power Control immediately adjusts the power level of the 4803CX LV. The
power supply does not need to be discharged between settings.
Turn Power switch to on position. The red Charge indicator will illuminate.
After a few seconds, the green Ready indicator will illuminate and an audible
beep will sound. (The beep will not be produced when a very small power
change is made. Changing the power level by a 1/3 f-stop or so is done very
rapidly with the 4803CX LV; the Ready light will usually remain on and the
beep will not sound.) The power supply is now charged to the selected level,
and ready to fire.
Do not immediately fire the unit on the first use or when the unit has been
idle for periods over 3 weeks. Allow several minutes for the power supply’s
capacitors to form. When the power supply has been used recently you may
fire the unit immediately. Push to Flash button may be depressed to verify
proper system operation.
When Power is on, be sure Ready indicator is illuminated before switching
Power or Fast/Slow. Do not move these switches while the unit is recycling.
When changing light ratios by moving light cables, we recommend that you
turn the power supply off. Though arc-protection is included with all
Speedotron systems, the safest method for changing ratios is to turn the
power off before moving the light unit cables.

8) Remote — for use with optional Remote Variable Power Control (#11237)
to allow exposure bracketing from the camera position. The Variable Power
Control must be in the full position for the power levels to be correctly
indicated by the remote control.
9) Sync — socket to connect power supply to camera or slave.
10) Power Input — socket for AC power cord.
11) Light Unit Outlets (6 – 4 standard, 2 for 206 light units only) — sockets
for connecting from one to six light units to power supply.
The 4803CX LV power supply will automatically discharge its storage
capacitors. Do not push the Push to Flash switch before turning power
supply off. This may damage power supply. Power supplies may flash their
light units when turned off. This is normal.
Unplug power cord from outlet, then disconnect light units from power
supply.
4803CX LV Power Ratios
Ratios apply to independent use of standard outlets. The four standard outlets represent:
1 - 800Ws single outlet, & 1 - 1600Ws single outlet which form the left channel; & 1 high power
double outlet which forms the 2400Ws center channel.
Explorer 1500
The Explorer 1500 is unique in the Speedotron
Black Line lighting system. It can travel throughout the
world using batteries that can be recharged on the local
power mains. The full line of Black Line lights and
accessories can now be used on location without the
need to haul bulky gas powered generators.
The Explorer 1500 is among the fastest, most
powerful battery powered flash systems in the world.
This is professional equipment and therefore it requires
some care on the part of the operator. All reasonable care and precautions
should be followed. The Explorer can overheat and be damaged if it is abused.
You can check this by simply placing your hand against the end of the case; if
it's too hot to hold your hand there, turn it off and give it a rest. Proper battery
maintenance is important for longest life, so read and follow the suggestions
in the Explorer 1500 Appendix.

the Power Pack at all times during operation. The
Power Pack receives all its power from the battery
even when the Explorer is plugged into the wall.
Attach the Juice Box to the Power Pack. The ON-OFF Switch on
the Power Pack must be in the OFF position. The plug on the Juice
Box connects to the plug on the bottom of the power pack. Insure that these
plugs connect and then latch the four fasteners at the ends of the units.
To change to a spare battery, turn off the ON-OFF Switch, open the
four fasteners as shown in the photo, (above) then lift the Power Pack off the

Battery life is estimated to be about 5 years if kept charged & not deeply
cycled. Battery life is reduced by deep cycling - the battery is limited to 300 to
500 full charge-discharge cycles. Reduced depth of discharge will give more
cycles.
It's OK to charge batteries while using the unit. This will insure the batteries
are kept in top condition.
It's OK to separate or mate the Flash Pack while the batteries are on charge.
DO NOT separate or connect the Power Pack to the battery while
the Power ON-OFF switch is turned on.
NOTE: Power is shared between the top high power outlet and the two left standard outlets (“X’s”
in the above diagram); power is also shared between the bottom high power outlet and the middle
two outlets. (“O’s” in the above diagram)
20
The battery can be used over a temperature range of -10°C (14°F) to 45°C
(113°F). Battery performance drops off rapidly below -10°C. Do not charge the
battery if the battery temperature is above 45°C.

When disassembling the system, turn Power switch to the off position.
5) Ratio Switch — Isolates or combines the two Light Unit Outlets. When the
Ratio Switch is in the A+B position, the entire pack is connected to both
outlets. If a single light unit is plugged into either outlet, it will receive the
whole charge from the capacitors. If two light units are connected, they will
share the power equally.

6) Light Unit Outlets — Two Black Line outlets accept existing Speedotron
Black-Line Light Units. The two outlets are labeled 1000 W-S and 500 W-S.
This is the maximum power that can be drawn from the outlets with the Ratio
Switch in the A/B position. Turning the Variable Level Control down from full
power will reduce the power available from both outlets, but the ratio between
the outlets will remain 2 to 1.
Fan-cooled light units will operate, but the fans will not run. This could cause a
build-up of heat that could damage the lights.

Explorer 1500 Description of Controls
1) Power — Turns power supply on and off. This switch controls only the
circuits inside the power pack section. Do not detach battery module while
the power is turned on. When this switch is turned on, the red POWER
LED will light, indicating that the unit is operating. When the power reaches
the voltage set by the Variable Level Control, the green READY LED will
come on and a brief beep will be heard.
Insure that this switch is in the off position when the Explorer
is transported or stored to prevent battery drain.
2) Modeling Light Switch — Spring-return switch starts the modeling
lights for 8 to 10 seconds. Pressing the switch again during modeling light
operation will have no effect. Pressing the switch immediately after the
modeling lights turn off will start another operation period.
Do not exceed 300 watts total between all model lamps. 100 or 150 watt
model lamps should be used. Do not use 250-watt model lamps - This
overloads the battery circuit! Modeling lamps should be used sparingly. A
single 10-second use of 150-watt model lamps uses as much battery charge
as two flashes at 1500 watt-seconds!
3) On LED — RED LED indicates power is turned on.
4) Ready LED — GREEN READY LED indicates that the capacitors are
within 1/10 F-stop of the value set by the Variable Level Control. Dialing the
control up or down will result in a not-ready condition and it will take some
time (not much!) to reach a ready condition again.
22
7) Variable Level Control — Controls power pack power for both Flash Unit
Outlets continuously from Full to Minus 5 f-stops. When power is dialed
down, an internal discharge circuit dumps only the power needed to reduce
the charge to the new level so battery power is conserved by not requiring the
Explorer to flash.
Hint: Battery power may be conserved when bracketing exposures by making
the lowest power exposure first and increasing power for the remaining
exposures. This reduces the need to dump power through dialing down.
8) Slave Trigger — The Photocell senses nearby flashes and fires the
Explorer. The slave trigger is disabled when a sync cord is connected. The
slave trigger responds only to rapidly increasing light levels, such as a strobe
flash. It is highly immune to ambient light of any level, including direct
sunlight. High ambient light levels reduce sensitivity - it is most sensitive in a
dark room, least sensitive in tungsten or sunlit areas.
9) Sync Socket — The Low voltage sync socket accepts a 1/4” phone plug.
The sync circuit applies less than 5 volts to the camera's circuitry. This is
compatible with virtually all cameras. When a sync cord is connected, the
photocell slave is disabled.
Low Battery Warning — A fully charged battery should give at least 200
full power flashes. After that a beeper will sound indicating the battery charge
is low enough to give only a few if any full power flashes. You should change
to a spare battery at this point since continued use will discharge the battery
far enough that the Explorer would quit operating. The Explorer will quit
before the battery is discharged to a point that will damage the battery, but the
battery should be recharged at the earliest opportunity.
Caution — This power pack does not power the fans in light units. Be aware
that excessive flashing or modeling light operation can cause overheating. The
modeling light power source in the power pack will run 300 watts of lights for
several 10-second intervals without overheating. It may run higher powers,
but DO NOT use higher power lamps! The Explorer will overheat! It CAN
overheat and damage itself if it is abused.

Background - Chemistry of Lead
A lead-acid battery wants to be kept charged to keep its chemical system in
equilibrium. For longest life, it should be kept at a constant voltage (the "float"
voltage) when not in use. If it stands uncharged, it will self-discharge over a
period of about one year at room temperature. The discharged state causes
degradation of the materials in the cells. Lead-acid batteries should be kept in
the charged state whenever possible.
3-Stage Charger
The best way to charge a multi-cell lead-acid battery is to slightly overcharge it
to equalize the charge state on all the cells. The overcharge cannot be
continued indefinitely because it eventually would dry out the cells through
electrolysis of the water in the electrolyte. A 3-stage charger is the best
design to accomplish this.
The charger operates in three modes:
Fast Charge Mode
A constant current in a reasonable range is fed to the battery to convert the
active materials to the charged state in a reasonable time. On the low end, the
charge rate must be high enough to keep recharge time in a reasonable range.
Most sealed lead-acid batteries want between 0.2 and 0.3 times the battery
capacity in amp-hours for the maximum charge current. A 9 amp-hour battery
wants between 0.2 x 9 AH = 1.8 amps and 0.3 x 9 AH = 2.7 amps for best life.
The battery can accept more current when at a low state of charge.
Fortunately, a low state of charge means the cell voltage is lower, so the
charger can deliver a higher current until the voltage rises to some limit.
Slow Charge Mode
Slow Charge Mode limits the voltage to a range around 14.4 volts at room
temperature, until all the cells become charged & the current falls to a lower
level.
Trickle Charge Mode
When charge current at the Slow Charge Mode voltage falls to about 1/4 of
the Fast Charge Mode current, all the cells in the battery are nearing full
charge. The voltage can then be reduced to the Trickle Charge Mode
voltage, around 13.6 volts at room temperature. At this point the battery is
between 90% and 95% charged. It will complete charging to 98% capacity
over the next 3 to 5 hours, and reach 100% capacity overnight. The battery
should be left on Trickle Charge Mode when not in use for maximum life.
Indicator LED
The indicator LED changes color from red to green when the charger switches
to Trickle Charge Mode. It may blink during the transition from Slow
Charge Mode to Trickle Charge Mode.
Temperature Compensation
The charging voltage limits are adjusted for temperature to avoid overcharge at
high temperatures and undercharge at low temperatures.
24
Power cord - Unit is supplied with a US cord. This can be replaced by any
GROUNDING 3-conductor power cord to fit local receptacles. Universal input
85-265VAC, 47-63Hz. The unit will work anywhere in the world.
Charge state LED
Red - Fast Charge
This indicates the Fastest charge period.
The charger operates at a higher rate and constant power is delivered until
the battery is 70-80% charged. After this period the charging rate slows to
complete the charge.
Green - Long term maintenance
The charger is operating in the Trickle Charge Mode.
Leave the battery ON CHARGE for longest life.
It takes a few seconds for the charger to start. When the LED lights (red or
green) the charger is operating. During the transition from Fast Charge to
Trickle Charge, the LED will blink green for up to a minute while the
battery voltage falls to the Trickle Charge level.
Temperature compensated charge voltage insures full charge at
any temperature without overcharge. See the specs for temperature range.
Battery life is estimated at least 5 years. Battery life is reduced by deep
cycling - the battery is limited to 300 to 500 full charge-discharge cycles.
Reduced depth of discharge will give more cycles.

Appendix --- Battery and Charger Details
• Unpack and examine all equipment carefully.
• Should you notice any breakage or defect, notify your dealer (and carrier if
it was shipped to you) immediately. The flash tube(s) and model lamp(s)
are packed in their original cartons. This affords sufficient protection and
reduces the incidence of breakage during shipping. Make sure all packing
materials are removed before using. This includes pipe cleaners (used as
packing material) inside flash tubes.
• Install model lamp and flash tubes. Always handle lamps and flash tubes
with care. Because they can break if put under stress, handle cautiously.
• Don't touch glass surfaces with your bare hands. When removing or
replacing lamps and tubes, always disconnect light units from power
supply.
• Allow lamps to cool before handling or installing protective tube covers.
• Flash tubes must be inserted into the sockets all the way. A slight rocking
motion may be necessary when installing the larger flash tubes. New flash
tubes and sockets fit very tightly. Be sure all flash tubes and model lamps
are fully seated into light unit sockets.
• All Speedotron Black Line flash tubes are designed to accept a minimum
of 2400Ws.
• Connect light cable(s) to the Light Unit Outlet(s) on the power supply. (For
the 202VF/206VF, connect the light unit cable to the light unit before
connecting to power supply).
• Never connect or disconnect light units while power is on. Do not insert or
remove flash tubes or model lamps while power is on.
• Speedotron power supplies are equipped with arc-protected outlets.
However, as with any electrical equipment, arc-over (an electrical
discharge between two physically disconnected electrical terminals) is a
possibility. When light cables or flash tubes are improperly seated, arc-over
may occur. Also, if your light unit or power supply malfunctions, or the
power cord or internal wiring in the studio is improperly terminated or
defective, there is a possibility of arc-over when connecting or
disconnecting the light units. Severe power supply damage and operator
injury may result if arc-over occurs. That is why in spite of the arcprotection feature of Speedotron units, you should always make sure
power is off when connecting or disconnecting light units.
• Install the desired reflector unto the light unit. Align the round notches on
the reflector with the nylon buttons on the light unit, then twist firmly
clockwise, (viewed from front and insuring that reflector assembly is
bottomed on mounting socket) approximately 1/4 of a turn. This should
securely mount the reflector into the light unit housing.
• Turn on power supply, wait for Ready light, then press Push to Flash
button to verify proper operation. At this time, if you have a fan cooled
unit (all except the 103), the fan should be operating. The model lamp is
controlled by the Model switch at the power supply. Some light units also
have a Model switch on the top or side of the light unit.
• For maximum performance and tube life, the model lamp should be used
only when necessary and turned off after initial set-up or focusing is done.
Although the forced air cooling is more than ample for normal usage,
turning off the model lamp will eliminate heat and enable the light to run
cooler, extending the life of all components.
• After extended use, inspect flash tubes for cracks and any unusual
darkening (arc-over) around the plugs. This is particularly important for
multi-tube flash lights. If cracks or darkening are noted the flash tube is,
most likely, near the end of its duty cycle. Cracked tubes will probably
misfire. The normal life expectancy is 100,000 flashes for the majority of
Speedotron Black Line flash tubes.
• Be sure replacement flash tubes are designed for the watt-second output
requirements of Speedotron light units. Never subject a flash tube to
more watt-seconds than it is designed to handle. Applying too much
power severely shortens the life of flash tubes, may cause fine cracks to
develop in the tube that may cause tube failure or, in the most extreme
case, may cause a tube to shatter. For this reason, we suggest you
always use Speedotron flash tubes and model lamps to insure safe and
dependable operation.
• Trigger voltage - New 1205CX LV, 2405CX LV, 2403CX LV, 4803CX LV
and all Explorer 1500 Power Supplies have Trigger Circuits of 6 volts or
less and should be safe for operation with all digital cameras. See your
camera’s instruction manual for specific voltage requirements.
Model 405 and 805 Power Supplies have a trigger voltage higher
than 6 volts and may require a low voltage sync adapter with some
cameras.
• Light units come with a 5/8" light stand mount. The umbrella bracket is
drilled to accept 3/8" diameter umbrella shafts - 5/16” on 202 and 206
(must be used with 7" reflector). The umbrella bracket may be moved to a
position closer to the light unit body to accept special umbrellas and
accessories. When using this alternate position the reflector will have to be
custom drilled to accept the umbrella shaft.

This general purpose, heavy duty light unit includes a quiet, highefficiency cooling fan. It comes standard with the 11.5" universal grid
reflector.
For operating instructions, follow the guidelines in the General
Information section of this manual.
This special purpose, fan-cooled heavy duty light unit has four 2400Ws
flash tubes supplied by two power cables. It can be powered by either
one or two power supplies. Each cable delivers power to two flash tubes;
when one has failed or is missing, the full power (up to 2400Ws) will be
sent to the remaining operational tube. Up to 4800Ws may be put
through the 2 cable 105. It comes standard with an accessory mounting
collar.
The cable that supplies power to the built-in fan and model lamp is
marked with a band.
Follow the general operating instructions in the General Information
section of this manual.

Speedotron has added this new slim-body traveler to its economical
and popular 100 Series. This compact light plugs into any Black Line
power supply and accepts any universal Black Line accessory. This
efficient convection-cooled unit is offered with color-corrected or clear
flashtubes which are rated to an ample 2400 watt-seconds maximum.
The switch on top of the light unit may be used to turn off the model
lamp.
For operating instructions, follow the guidelines in the General
Information section of this manual.
Model 202VF Light Unit
This extremely portable, modular, heavy duty light unit has noiseless
fan cooling. Reflectors mount to the red focusing collar, offering a wide
range of coverage.
Assembly of the 202VF is simple. Attach the pan-tilt bracket to the right
side of the light unit with the thumb screw. Turning the pan-tilt bracket
handle counter-clockwise allows one-handed positioning of the 202VF.
The light unit cable must be attached to the 202VF before connecting to a
power supply. Align the flat surface of the molded strain relief plug with
the outlet at the back of the light unit. Push the cable straight in, and give
the locking ring a 1/3 clockwise turn, until it "clicks".
The red focusing collar is normally mounted with the nylon button
forward (although reverse mounting may be better for customized soft
boxes or other special-use applications). With a reflector mounted and the
focusing collar in the fully forward position, narrow angles and high guide
numbers are achieved. When rotated fully back (about 2 full turns), the
widest angles and the lowest guide numbers are achieved. The best
general results with Speedotron universal reflectors is at the midpoint,
about 1 turn back. For soft box use, the fully back position will generally
be best.
Umbrellas are mounted through the hole in the 7" umbrella reflector for
202VF, limiting the movement of the focusing collar to four positions.
The black switch on the side of the light unit may be used to turn off
the model lamp.
For other operating instructions, follow the General Information section
of this manual.

Trouble-shooting
All Speedotron Black Line equipment is ruggedly built.
Nevertheless, it should be treated with the same care given to
other pieces of quality photographic equipment. To protect
the user, all Speedotron equipment is designed to be safe
when used in accordance with instructions. To assure the
maximum in safe, dependable service, the following
guidelines should be carefully observed.
System will not work at all; no flash.
Check that sync cable, AC power cord and light unit cables are firmly and
properly attached. Check that the flash tube is firmly seated. Check that
Power switch is on.
• Avoid kinking or pulling cables. Disconnect cables by pulling on the
quick release only, except for the 206 light unit which has a threaded
ring. Never pull plugs out by the cable. Light cables as well as sync
cords and AC power cords should be occasionally checked for wear,
cracks, separation between cable and plug, and for indications of arcover.
• Do not wrap the light unit cables around the light units. Coiling cables
tightly stresses the internal wires and may lead to premature cable
failure. If possible, keep the coil diameter at least 10 inches.
• If a cable becomes frayed, the insulation damaged, or the connectors
bent or broken, have them repaired immediately.
• Keep all connectors, plugs and sockets free of dust, moisture and
corrosion.
• Do not connect or disconnect light units or insert or remove flash
tubes while the power supply is on.
• When using your equipment, be sure all cable, sync, power and flash
tube connections are completely and properly installed.
• Do not attempt to make repairs to your Speedotron equipment
yourself. It is very dangerous, and will void your warranty. Consult your
dealer regarding authorized service in your area, or return the
equipment to Speedotron. When you are not using your equipment, it
is recommended that you store it in a dry place. Equipment should be
charged up and flashed a few times at least once a month. This will
keep your equipment in top working condition for many years.
• With your light unit disconnected, occasionally remove the reflector
and clean the interior surface with a light solvent or soap and water.
Carefully remove the flash tube, and clean the glass cover. Only in this
way will you conserve a consistent color temperature and light output.
Dirt and dust deposits on the tube and reflector act like a filter to alter
color.
• To extend the life of the model lamp, it should be turned off after setup and focusing.

Check flash tube; check power supply by comparing to similar pack with
same light units if possible.
Flash tube glows after a flash (afterglow) and will not flash again
until glow is gone.
If confined to one light unit, check flash tube by substitution. If it
continues or all lights afterglow, power supply is at fault. If this is the
case, turn power supply off immediately! Power supply needs repair.
Ratio or Variable Power Control switch has no effect on recycle time
or light output.
Power supply needs repair.
Circuit breaker on power supply pops.
Check that all cables on power supply and light units are properly
connected. Also check for afterglow. If a circuit breaker blows, it is an
indication that something is wrong. Normal operation will not blow circuit
breakers.
Circuit breaker or fuse in studio blows.
Use slow setting on Recycle rate switch.
Model lamp fails to light on one light unit.
Check that the model lamp switch on that light unit is in the “ON”
position.
When checking power supplies, light units and cables, be sure that
Power is off. Look for blackened, discolored or burned pins and sockets.
If a Light Unit Outlet on the power supply is burned, blackened or
discolored, it must be replaced before it is used. It could damage light
units that are connected to it. Check that cables are not loose or frayed.

SPECIAL CHARACTERISTICS
If power is reduced by using the dial-down knob, durations will remain the same. All durations tested in accordance with ANSI PH3.40
Section 2; “The time interval from the instant the flash reaches one-half of its peak intensity to the instant it decays to the same value”.
*These power levels are reached by the use of the 14202 adapter cable & a standard outlet.
**Flash duration of 103 light unit using the 405 power supply: 400Ws = 1/500sec.;
and using the 805 power supply: 800Ws = 1/300sec., 400Ws = 1/500sec.
