Input Under-voltage
Feature Description
CNT Function
The modules have the CNT control function
(CNT pin), which can control module output
“ON” or “OFF” while the input power does not
changed. “Control” is accomplished at the
primary side. For AVE40-48RNG-6, the
positive logic module, when CNT is connected
with -Vin or suspended, output is OFF. When
CNT is connected with + Vin, output is ON. For
AVE40-48RNGN-6, the negative logic module,
when CNT is connected with -Vin, output is
OFF. When CNT is connected with + Vin or
suspended, output is ON. Working current of
CNT is related to the input voltage. CNT
function can realize by either (of switcher or
relay) simple mode, or by transistor series in
CNT. Isolated control may be needed in some
cases, where the opto-coupler or relay must
be used. When the control cable is long, it is
recommended to parallel a 0.1µF capacitor
between CNT and –Vin. CNT should be
connected directly with + Vin or suspended
when CNT function is not needed.
There is input under-voltage protection
circuit inside the module. When the input
voltage is lower 65%
~
75% of
nominal input voltage, under-voltage
protection active, and output is
shutdown. There is 1.5V hysteresis error
between under-voltage shutdown and
under-voltage restart.
Figure 4 input under-voltage protection
Output Over-current Protection
There is OCP protection circuit inside the
module, and when output current is over 125%
~ 175% of the nominal output current, the OCP
protection will active (no bias connection)
When the over-current protection is active, the
module is in interim working mode. That is to
say: when short-circuit occurs in the output
end, the over-current protection circuit works
to shut down the output. Then the module
restarts after 1 second. If the short-circuit still
exists, the output is shutdown again, and
repeat so back and forth. If the over-current
condition is removed, the output of the module
is automatically recovery.

Fusing
There is protecting circuit inside the module, to
improve the safety, it is recommended that
connect a common fuse with input of module.
The recommended value is 5A.
Design Consideration
Figure 6 Bias application
Input Reverse Protection
No Bias Connection
Under installation conditions where reverse
polarity across the input may occur, reverse
polarity protection is recommended. Protection
can easily be provided as following figure 7.
Diodes should be 1A/100V common type.

No bias application
Bias Connection
AVE40-48RNG-6 series can only work in
this bias connection mode, other bias
connection mode is forbidden.

Note: AVE40-48RNG-6 cannot be used in

Insulation Strength Testing
Thermal Consideration
During the insulation strength testing, increase
voltage gradually. Testing voltage is 500Vdc
for I minute. When finish the testing and shut
down the insulation strength testing equipment,
it should decrease testing equipment voltage
to zero gradually, and then turn off the power
switch. Especially to the insulation strength
testing equipment with timer, it must not use
the timer, or it will cause several times voltage
on the module.
When the working temperature is above 55°C,
the module works in derating. The derating
curve under natural convection is as following
figure 11.

The MTBF, calculated in accordance with
Bellcore TR-NWT-000332 is 2,000,000 hours.
Obtaining this MTBF in practice is entirely
possible. If the case temperature is expected
to exceed + 25°C, then we also advise an
oriented for the best possible cooling in the air
stream.

Techanical
Consideration
Installation
The converter can be mounted in any
orientation, free air-flowing must be taken.
Normally power components are always put at
the end of the airflow path or have the
separate airflow paths. This can keep other
system equipment cooler and increase
component life spans.
Soldering
The converter is compatible with standard
wave soldering techniques. When wave
soldering, the converter pins should be
preheated for 20-30 seconds at 110°C, and
wave soldered at 260°C for less than 10
seconds.
When hand soldering, the iron temperature
should be maintained at 400°C and applied to
the converter pins for less than 5 seconds.
Longer exposure can cause internal damage
to the converter. Cleaning can be performed
with cleaning solvent IPA or with water.

TRIM：Pin to adjust amplitude of output voltage.
The output voltage can be adjusted from 65VAC to 95VAC by insert a resistance “Roac”
between pin “TRIM” and “GND”.
When Roac=23.113kohms, the
output voltage is 65VAC
When Roac=0, that is, “TRIM”
connects directly to “GND”, the output
voltage is 95VAC
When Roac changes between 0～
23.113kohms, the output voltage
changes between 95VAC and 65VAC,
too.
The TRIM formula is:
Roac =
1292 / 23
