Power Resistors General Information

Power Resistors
General Infornation
Providing Design Engineers with an Economical Power Resistor
Providing design engineers with an economical power resistor with high quality performance, Token
Electronics offers industry grade wirewound power resistors.
Products range from large capacity metal clad, nonflammable fixed and adjustable, wave ribbon
wire-wound, slide, starter, box type, to nonflammable flat type. Token extends a complete line of
power wirewound resistors for both military and commercial applications.
Benefits & Features
Token provide terminal blocks, thermal switches, fusing, fans, junction boxes, screened or solid bottom plates, conduit knockouts, and customer specified requirements. For large applications a welded
frame construction is utilized to provide a robust design for power resistor mounting in both indoor
and outdoor environments.
Utilization Notes
1. Smoke emitted from non-flammable resistors on initial use in powered circuits is a normal
phenomenon and the component can be safely utilized.
2. All resistors manufactured by Token Electronics Industry Corporation comply with the U.S.
UL-94 non- flammability test, Class V-0, a continuous combustion period of zero seconds.
3. Never use organic solvents to clean non-flammable resistors.
4. Non-flammable resistors cannot be utilized in oil.
5. Non-flammable resistors cannot be used in high frequency machinery because of the inductance
produced by the windings. A suitable type of resistor must be selected. Contact us for details.
6. In applications where resistors are subject to intermittent current surges and spikes, be sure in
advance that the components selected are capable of withstanding brief durations of
increased load.
7. Do not exceed the recommended usable load. Resistors must used within the rated voltage
range to prevent the shortening of service life and/or failure of the wound resistance elements.

Power Wirewound Resistors
8. Minimum load. Resistors must be utilized at 1/10 or more of the rated voltage to prevent poor
conductance due to oxidation build-up.
9. Although the hardness exceeds that of a 3H pencil lead, do not nick the resistor coating with screw
drivers or other pointed objects. 10. Avoid touching non-flammable resistors in operation; the surface
temperature ranges from approximately 350°C ~ 400°C when utilized at the full rated value.
Maintaining a surface temperature of 200°C or less will extend resistor service life.
11. Keep temperature from rising by choosing a resistor with a higher rated capacity; do not use a
component having the exact load value required. For considerations of safety in extended period
applications, the resistor rating should be more than four times higher than the actual wattage
involved, but never use a resistor at less than 25% of its rated power.
12. Application and Placement: Wire-wound resistors use different gauges of wire as resistance
elements. Sometimes the gauge is extremely thin (finer than a strand of human hair) and very
susceptible to breakage in environments containing salts, ash, dust and corrosives. Avoid utilization
in such environments. Do not install in dusty areas because the accumulation will cause shorts and
poor conductance.

Power Resistors Terminology Glossary
Wire-wound
Power Resistors
Terminology Glossary
Ayrton-Perry Winding
Winding of two wires in parallel but opposite directions to give better cancellation of magnetic fields
than is obtained with a single winding.
Wirewound technology has long been known as a leading technology for power resistor needs. The
most critical drawback with this technology is that it is inherently inductive. This is logical given that
a wirewound inductor and a wirewound resistor are made with essentially the same materials and
processes. This fact limits the use of wirewounds for applications with high switching speeds, which
require low inductance.
Now the same standard wirewounds can be used for these applications by using a non-inductively
wound version. This manufacturing method greatly reduces the inductance of any given resistor size
and value combination, however it does not completely eliminate the inductance. A non-inductively
wound wirewound has one winding in one direction and one in the other direction; known as Ayrton
Perry winding. This non-inductive winding is available in all Token standard wire-wound resistor
series.
Dynamic Braking Resistors
Dynamic braking resistors are used on VFDs (AC variable frequency drives) to dissipate energy that
is produced in the motor as the drive provides braking torque to stop the motor. The resistors are
either used alone for decelerating or in conjunction with compressed air brakes for stopping. The excitation voltage of the traction motors generally comes from a static converter powered by the overhead
catenary and operates as a DC voltage transformer.
Token’s BOX, and RNW wirewound resistors are used for most dynamic braking applications. These
are conveniently provided on L-shaped mounting brackets or in standard enclosures with louvered
or screened covers. For heavy duty applications that require even higher wattage, we recommend
Token’s Oval Edge-Wound DOE, and Power-Wound DST resistor elements.
Neutral Grounding Resistor
A suitably rated power resistor that is connected between the neutral of a transformer (or generator)
and the system ground. It serves to limit fault currents and prevent damage to the equipment.

Power Resistors Terminology Glossary
Rated Continuous Current
The current expressed in amperes (RMS), that the device can carry continuously under specified service
conditions without exceeding the allowable temperature rise.
What is a Ground Fault
A Ground Fault is an unwanted connection between the system conductors and ground. Ground faults often go unnoticed and can cause problems with plant production processes. They can also shut down power
and damage equipment, which disrupts the flow of production leading to hours or even days of lost productivity.
Undetected ground faults pose potential health and safety risks to personnel. Ground faults can lead to
safety hazards such as equipment malfunctions, fire and electric shock. Ground faults cause serious damage to equipment and to your processes. This damage can seriously affect your bottom line.
Power Dissipation
This is a measure of the amount of power that a resistor can dissipate without causing it to overheat. Resistors are manufactured in standard power ratings and mostly these are in fractions of 1 Watt with some
larger carbon and metal resistors available in 1 Watt to about 5 Watts. Higher power ratings are available.
Wirewound resistors are normally available in power ratings of up to about 50 W. However, industrial
wirewound types are made by component manufacturers in much higher power ratings to the specification
of the customer.
Industrial Variables & Adjustable Wirewound Resistor - Resistive Controls
Controls that produce a varying voltage using resistance are called either adjustable or variable resistors
(potentiometers). Although both types of control may be functionally the same, it is the way they are connected that differentiates between the two types.
A common construction is for the control to have three connections. One connected to a sliding contact
called the wiper and the other two to either end of a fixed resistor called the track. The wiper is able to be
moved along the track either by use of a linear sliding control or a rotary “wiper” contact. Both linear and
rotary controls have the same basic operation.
High Power Wirewound Resistors
Industrial high power wirewound resistors are high temperature, high power non-inductive resistor types
generally coated with a vitreous or glass epoxy enamel for use in resistance banks or DC motor/servo
control and dynamic braking applications. The resistance wire is wound around a ceramic or porcelain tube
covered with mica to prevent the alloy wires from moving when hot. Wirewound resistors are available in
a variety of resistance and power ratings. With one main use of High Power Wire-wound Resistor is in the
electrical heating elements of an electric fire which converts the electrical current flowing through it into
heat with each element dissipating up to 20000W, (20kW) of energy.

TOKEN
Power Resistors Terminology Glossary
Because the wire is wound into a coil, it acts like an inductor causing them to have inductance as well as
resistance and this affects the way the resistor behaves in AC circuits by producing a phase shift at high
frequencies especially in the larger size resistors. The length of the actual resistance path in the resistor and
the leads contributes inductance in series with the “apparent” DC resistance resulting in an overall impedance path Z. Impedance (Z) is the combined effect of resistance (R) and inductance (X), measured in ohms
and for a series AC circuit is given as, Equation Z2 = R2 + X2.
When used in AC circuits this inductance value changes with frequency (inductive reactance, XL = 2πƒL)
and therefore, the overall value of the resistor changes. Inductive reactance increases with frequency but
is zero at DC (zero frequency). Then, wirewound resistors must not be designed into AC or amplifier type
circuits where the frequency across the resistor changes. However, Token offers special wirewound non-inductive resistors winding Ayrton-Perry Method are also available for alternative choice.

Power Resistors
Application Notes
Determination of End Resistance Value of FVR, DQS, DSRA, DSRB, BSR, BSQ:
● Resistance Range means you can choose one maximum resistance value (End resistance value)
at one of FVR, DQS, DSRA, DSRB, BSR, BSQ VR (Variable Resistor) type.
● After End Resistance Value confirmed, the minimum resistance (start resistance value) will be
determined by depending on resistance of wire and wirewound type.
Power Rating of Variable Resistor:
The part Nunber formation of FVR, DQS, DSRA, DSRB, BSR, BSQ:
Product type
-
Rated Wattage
-
Resistance Value (Ω)
- Resistance Tolerance
Product type means one of FVR, DQS, DSRA, DSRB, BSR, BSQ.
Rated Wattage means power rating at End Resistance Value.
Resistance Value (Ω) means maximum resistance value (End Resistance Value).
Resistance Tolerance means precision range of End Resistance Value.
1. Power Rating of VR (Variable Resistor) is determined by the maximum resistance value
(End Resistance Value).
2. Resistance and Power Rating should be decreased while you are adjusting the screw.
Notes:
● Adjustability is 10% to 90% of full resistance value.
● Wattage is proportional to this adjusted resistance value.
Power Rating:
● Based on 25°C free air rating. The stated wattage rating applies only when the entire resistance
is in the circuit.
● Setting the lug at an intermediate point reduces the wattage rating by approximately the same
proportion.
● Example: If the lug is set at half resistance, the wattage is reduced by approximately one-half.

Token Electronics extended lead wire aluminum housed
power AHL series provides design engineers a flexible
connection in distance between connections
AHL is a high-performance axial-terminal type resistor
with flexible connections. These molded-construction
aluminum-chassis resistors are available in higher power
ratings than standard axial-terminal resistors and are
better suited to withstanding vibration, shock and harsh
environmental conditions.
AHL resistors are aluminum housed to maintain high
stability during operation and to permit secure mounting to chassis surfaces. The metal housing also provides
heat-sinking capabilities, allowing the units to exceed the power ratings.
The AHL Series is RoHS compliant and lead free. For non-standard technical requirements and custom special
applications, please contact us for details with your specific needs.
Non-Inductive :
Ayrton Perry type non-inductive winding is available. When required add “N” to the part number.
Features :
● High stability, strong construction.
● Standard winding & non-inductive winding types.
● High power rating, small size and ultra precision.
● Aluminum housing allows chassis mounting and provides heatsink capability.
General Specification :
● Resistance Tolerance: ±10%, ±5%.
● Operating Temperature Range: -55°C to +275°C.
● Wattage Range: 4 styles to choose ranging from 25 to 150 watts.
● Dielectric Strength: AHL-25 1000V, AHL-50 1500V, AHL-150 2500V.

DQ Tubular Wirewound Power Resistors
Wave-type Tubular
Wirewound
Power Resistors
Wave-Shape Ribbon-Wound Design
Neutralize Inductance Parasitoid (DQ)
Preview
Ribbon-Wound Power Resistor Construction:
● A tubular ceramic has two terminals, and is wound with a resistance element consisting of a
wave-shaped alloy ribbon.
● Terminal bands are spot welded after installation on the core and then a
resistance-alloy ribbon wire is crimped
and edgewound onto the core.
● Non-flammable resin insulation is applied
after cooling and drying through a
temperature process and then the
component mounts are attached.
● The resistance value range is relatively low
due to alloy material limitations; see the
DR series if upper resistance values required.
Features:
● Fixed, tapped styles, or adjustable type are available.
● Special terminals are available for unusual applications.
● Special tolerances, temperature coefficients, and resistance value can be specified.
● Ayrton Perry type non-inductive winding formats are available. See DQS Series when requied.
● Standard resistance tolerance is H(±3%), J(±5%) and K(±10%). Closer tolerances are available upon request.
● The wire is spot welded to the terminal bands and then “fastened” onto the core with a silicone, cement, or
vitreous enamel coating.
● Standard lug terminals available with or without terminal hardware. Single and double quick connect
terminals can be specified.
● DQ Series Design allows for efficient heat dissipation at higher temperature ranges so the resistor is
half the physical size of an equivalent rated roundwire resistor.
Applications:
● The Power Ribwound DQ Series is suitable for educational modeling applications, load testing, industrial
machinery, electric power distribution, instruments, automation control installations, lift trucks, overhead
cranes, elevators, arc and spot welders, battery chargers, machine tools, conveyors, and UPS systems.
Power Wave-Shape Ribwound Resistor supports the use of numerous taps, has low impedance, and can be
fabricated in various shapes to support a wide range of applications.
The DQ Series is RoHS compliant and lead free. For custom specifications, or order individual replacement
units, entire grids with various mounting configurations, please contact us to discuss the details.

Ribbon Wirewound
Power Resistors
Preview
DQ-*N Power-Rib resistor applies Ayrton Perry non-inductive winding method to compensate residual
inductance and to allow for efficient heat dissipation at higher temperature ranges, so the resistor is half the
physical size of an equivalent rated round wire wound DR resistors.
Non-Inductance :
Ayrton Perry type non-inductive winding is applied. When required add “N” to the part number.
Resistance Tolerance :
K(±10%), J(±5%), H(±3%)
The power DQ-*N Wave-Ribbon Series is lead-free and RoHS compliant. Please contact us for
details with your specific needs.

DR Round-Wirewound Power Resistors
Round-Wirewound
Power Resistors
The Best Cost-Effective Power Resistor
for High Energy Applications (DR)
Preview
Features:
● Fixed, adjustable, or tapped styles are available.
● Special terminals are available for unusual applications.
● Special temperature coefficients, tolerances,
and resistance value can be specified.
● Ayrton Perry type non-inductive winding formats
are available. See DRS Series when requied.
● Standard resistance tolerance is ±5% and ±10%.
Closer tolerances are available upon request.
● Standard lug terminals available with or without
terminal hardware.
● Single and double quick connect terminals
can be specified.
● The wire is spot welded to the terminal bands and then “fastened” onto the core with a silicone, cement,
or vitreous enamel coating.
Round Wire-wound Power Resistor Construction:
● A tubular ceramic has two terminals and is wound with copper roundwire or chromium alloy roundwire
to provide the resistance.
● Coated with non-flammable resin in high temperature. Insulation is applied through a high-temperature
process and the mounts are attached.
● Due to Token excellent winding technolgy applied , many taps can be added, impedance is low and the
shape can be altered to produce many types.
Applications:
● Ideal for educational modeling applications, load testing, industrial machinery, electric power
distribution, instruments, automation control installations, etc.
● Typical applications for roundwire DR series in motor/motion control include areas such as dynamic
braking, motor starting, speed/torque control, industrial machinery, electric power distribution, and plugging.
● Other applications include load dumping, current limiting, elevators, UPS systems, lift trucks, and
voltage dropping.
The DR Series is RoHS compliant and lead free. Order individual replacement units, entire grids with various
mounting configurations, or custom specifications, please contact us to discuss the details.

Token DOE Series are commonly used as a dynamic braking resistor on Transit applications. Built to perform
in rugged environments, they feature corrosion resistant stainless steel insulator supports, solid nickel terminals,
and special electroless nickel-plated solid copper terminal supports.
The resistance element is made of a stainless steel resistance alloy. Terminals are welded or silver brazed to the
oval, spiral edge-wound resistance element. Toothed ceramic insulators isolate the resistance element from the
center support. Ceramic end bushings insulate the center support from the mountings.
Order individual replacement units or entire grids with various mounting configurations.

ZR Flat-Wirewound Power Resistors
Oval Flat-Wirewound
Power Resistors
When Limited Space is Required,
Choose Token’s “Thin” Stackable (ZR) Resistors
Preview
Token oval-shaped ceramic-core resistors
feature a low profile to permit installation
in spaces with height restrictions.
They are also equipped with integral mounting
brackets so they can be fastened to a chassis
and stacked in locations with limited surface
area. When properly fastened, the mounting
brackets add a heat sinking benefit resulting
in a smaller size per watt. Durable ZR power
resistors are fully welded and coated with lead
free non-flammable resin.
ZR resistors are suitable for educational
modeling applications, load testing, industrial
machinery, electric power distribution, instruments, automation control installations, etc.
The ZR Series is RoHS compliant and lead free. For non-standard technical requirements and custom special
applications, please contact us.
Non-Inductive :
● Ayrton Perry type non-inductive winding is available. When required add “N” to the part number.
Construction :
● Wirewound ZR Resistor is a flat tubular ceramic rod has two terminals and is wirewound with either
copper wire or chromium alloy wire as a resistance element.
● Mainly utilized for industrial installations where height is limited. Features excellent windings, taps
adding, low impedance, and PC board insertable.
Notes :
● When resistors are stacked, use washers or spacers as required to insure clearance and improve power
dissipation.

Power Resistors
High Starter Power Suitable for
Application Loads Involving Brief Current Surges
Preview
DST Power Resistor Construction:
● A tubular ceramic insulator has a fixed number of windings and is wound with heavy alloy wire as
a resistance element. The staggering wound is made according to the desired resistance value,
followed by the placement of the component mounts.
● Metal parts are heavily plated to prevent oxidation at high operating temperatures and to prevent
corrosion. DST’s high power rating (500W~1000W) and low resistance value (0.5Ω-7Ω) provide
applications high starter power and capacity.
● This power wirewound resistor is high temperature-resistant, dissipates heat well, has a low
temperature coefficient that varies in direct proportion, and is suitable for application loads involving
brief current surges.
Applications:
● Typical applications for power strater resistors in motor starters, load measurements, industrial
machinery, electric distribution, dynamic braking, load dumping, current limiting, instrumentation,
and automation control installations.
● Due to the set number of windings on the ceramic form, the resistance value range is relatively
low. Tolerance is ±10% and this product is available in various shapes or in resistance boxes.
The DST Series is RoHS compliant and lead free. For non-standard technical requirements and special
applications, please contact us.

Power Resistors
C-shaped Wirewound Variable Resistors - FVR Series
Rheostat, Variable Resistors
Control The Speed of a Motor
Preview
Token’s Power Variable Resistor FVR Series is a C-shaped
ceramic rod and wound with copper or chromium-alloy wire
as a resistance element. Except for the slide contact surface,
the entire component is coated with a high-temperature,
non-flammable resin. After cooling and drying, insulation
is applied through a high-temperature process. Then, a
centered rotating adjuster component is installed, which
slides along the resistance element and varies the resistance
to the desired value.
Variable Resistors are often called potentiometers in books
and catalogues. Variable FVR may be used as a rheostat
with two connections (the wiper and just one end of the
track) or as a potentiometer with all three connections in use.
Applications :
● Motor controller also use FVR Series as rheostats or potentiometer to control the speed of a motor by
limiting the flow of current through them.
● They are used in many small appliances such as blenders, mixers, fans, and power tools.
● FVR Rheostats Series are also used as test instruments to provide an accurate resistance value.
● While FVR can be used to control electric ovens and cooktops, thermostats are preferred because they
have additional parts which automatically adjust the current flow to maintain a constant temperature.
Features :
● Standard resistance tolerance is K(±10%). Closer tolerances are available upon request.
● 3 Wattage Rating styles to choose: 25W, 50W, and 100W.
● Wide Max. Resistance range: 5Ω ~ 5KΩ.
The FVR Series is RoHS compliant and lead free. For non-standard technical requirements and custom special
applications, please contact us.

Low-Cost and High-Precision
Power Adjustment Resistors for High Energy Dissipation
Preview
Adjustable Ribbon-Wound Power Resistors have been
a main product line at Token Electronics for years.
Ribwound adjustable resistors are particularly useful
where high energy is to be dissipated in the lower
ohmic ranges and high power capacity. Precision
winding design, provide uniform windings to be
applied extremely close to each other resulting in
significantly higher resistance values.
In significant savings in space and cost,
Adjustable DQS Series is ideal replacements
for many standard round-wire resistors.
Features :
● Resistance Tolerance: K(±10%), J(±5%), H(±3%).
● Power-rib wirewound resistor with adjustable lug supplied.
● Suitable for high energy to be dissipated in the lower ohmic ranges.
● Design as heavy-duty resistors to withstand frequent start-stop cycles.
● Hollow core to permit secure fastening with spring-type clips or thru bolts with washers.
● Durability Flame resistant coating and all-welded construction.
● Terminals suitable for bolt connection or soldering.
Power Rating :
● Based on 25°C free air rating. The stated wattage rating applies only
when the entire resistance is in the circuit.
● Setting the lug at an intermediate point reduces the wattage rating by approximately the same proportion.
● Example: If the lug is set at half resistance, the wattage is reduced by approximately one-half.
● Wattage is proportional to this adjusted resistance value.
● Adjustability is 10% to 90% of full resistance value.
Options :
● Adjustable, fixed, or tapped styles are available.
● Special terminals available for non-standard applications.
● Single and double quick connect terminals can be specified.
● Standard lug terminals available with or without terminal hardware.
● Non-inductive Ayrton Perry windings can be specified.
● Special temperature coefficients, tolerances
To Calculate Max. Amperes :
● Voltage = (Watts x Ohms) 1/2
The Power Adjustable DQS Resistor is RoHS compliant and lead free. For unusual technical
requirements and custom special applications, please contact us.

BWW Precision Wirewound Resistors
Application Notes
Precision Wire-wound Resistors Application Notes:
● When being used in AC circuits, some wirewound structures give inductance ingredients or parasitic
capacity, so they may cause unusual phenomena such as oscillations etc. Quorum deviations of other components should be carefully taken into account for use.
● Application and Placement: Wire wound resistors use different gauges of wire as resistance elements.
Sometimes the gauge is extremely thin (finer than a strand of human hair) and very susceptible to breakage
in environments containing salts, ash, dust and corrosives. Avoid utilization in such environments.
● Do not install in dusty areas because the accumulation will cause shorts and poor conductance.

Wirewound Resistors are Getting Economical Solution
to Board Population
Preview
Token has launched its commercial wirewound resistor yet with the introduction of the various package size.
Matching price with size to provide an economical solution to board population, Token’s wire wound resistors
are available in 15 standard size power ranging from 0.5W to 12.5W, all at 1%, 2%, and 5% tolerance.
The KNP series has been designed to give enhanced pulse handling capability and increased flameproof
protection. The series is RoHS compliant with Pb-free terminations, and KNP wire-wound series can also be
supplied with radial, goalpost or lancet preformed leads.
The KNP drive to miniaturise is as widespread within industrial process control and circuit break products as
it is in the consumer sector. These resistors are ideal for high reliability industrial application as the technology
removes the excessive temperature risk.
Produced on a high purity ceramic substrate, the resistor is assembled with interference-fit end caps to which are
welded terminations. The resistive element is wound on the substrate and welded to the caps. Flameproof silicone
cement coating is applied prior to marking with indelible link. The components are then leadformed, if required.
To address your need for technical and economic success in a timely manner, our custom solutions are available.

Application Notes
Wire-wound Resistors Application Notes:
● When being used in AC circuits, some wirewound structures give inductance ingredients or parasitic
capacity, so they may cause unusual phenomena such as oscillations etc. Quorum deviations of other
components should be carefully taken into account for use.
● Application and Placement: Wire wound resistors use different gauges of wire as resistance elements.
Sometimes the gauge is extremely thin (finer than a strand of human hair) and very susceptible to
breakage in environments containing salts, ash, dust and corrosives. Avoid utilization in such
environments.
● Do not install in dusty areas because the accumulation will cause shorts and poor conductance.

Wirewound Resistors
Non-inductive Wirewound Resistors
Improves Inductance for High Frequency Applications
Preview
Token Electronics has introduced a non-inductive version KNPN Series of conformal coated, leaded wire-wound
resistors.
The KNPN series offers the expected performance of a wire wound resistor with the added characteristic of
vastly improved inductance, making it suitable for high-switching applications.
Wirewound technology has long been known as a leading technology for power resistor needs though it is
inherently inductive. Known as Ayrton Perry winding, a non-inductively wound wirewound has one winding in
one direction and one in the other direction.
By using a non-inductively wound version this greatly reduces the inductance of any given resistor size and value
combination; however, it does not completely eliminate the inductance.
This non-inductive winding is available in all standard KNPN sizes from 0.5 watts up to 6 watts with options
1%, 2% and 5% tolerance. The KNPN series is RoHS compliant and also can be supplied with radial, goalpost or
lancet preformed leads.
To address your need for technical and economic success in a timely manner, our custom solutions are available.
Contact us with your specific needs.
