Variable resistor value for REF-PV （VR1） ［Ω］
* Adjustable output voltage within 20% (3Vmodel : 30%) of
output (less than 1V of PV voltage) is proportional to PV
voltage and has a linear characteristic. However, for output
voltage within 10% of output (about less than 0.5V of PV
voltage), output will go into intermittent mode and ripple voltage
becomes large, also irregular sound is release from the power
supply. However, it is not damage. There will also be cases
of the power supply shutting down triggered by under voltage
lock out protection function. With output shutting down, low
output detection function (PF) triggers the PF signal and set it
to "H", and also output LED is switch off . Under voltage lock
out protection mode, switch off input for a few minutes and
then switch on input again for recovery. Recovery from under
voltage lock out is also possible by turning remote ON/OFF
control signal OFF and ON. Under voltage detection value uses
an automatic tracking mode, which follows the output voltage
and constantly correspond to the 70% -80% of output voltage
with a protection function mode. Base on the explanation above,
we will kindly exclude the usage of adjustable output voltage
within 20% of the output voltage from the product warranty. For
application that requires variable output voltage within 20% of
output voltage, please kindly consider the above contents prior
to operation. For application that requires output voltage below
20% , due to diff erent type of application for the user's system,
there might be a situation ( behavior ) different from the one
mentioned above. Therefore please check with the user system.
Output Peak Current
For model with output peak current, please meet the fol-
lowing condition.
Reduce peak current value according to output derating as
section 4-1.
The output is shut down by protection circuit when rated
current and continuous peak output time (τ) exceeds
rated value during usage.
When protection circuit is activated, input is temporarily
cut off for a few minutes and then power is re-input or re-
mote ON/OFF control signal should be input for recovery
of the output.
Continuous Peak output time.（τ）：Within 10 seconds
Peak output current（Ip）：Within the rated peak output current

Input Open Phase Detection
If one of the 3-phase input line becomes open or one
phase voltage falls below 160VAC, the output will be shut
off in approximately 3 seconds. To restore the output to
normal, shut off the input once, and apply a normal input
line voltage again after for a while.
