Specifications

3. REMOTE MONITORING AND INDICATIONS . A 25 pin D-sub connector has
been provided for remote monitoring and indication. Pin connections are given
below. Pins 2 and 16 are meant to indicate availability of input AC power. Cur-
rent indication on pins 18 & 6 is 0.5mV per Amp. (Shunt ratio 25mV / 50A)
ITEM NUMBER ID FUNCTION
PROTECTIONS
SHORT CIRCUIT PROTECTION : In the event of a short circuit, the PWM controller
will be shut down and the output will drop to near 0 V. The green LEDs will flash.
The unit will reset automatically once the short circuit condition is removed
CURRENT LIMITING : The unit will enter this mode when the load tries to draw
more than the limiting values of currents as shown in the specifications. Under this
condition, there will be loss of voltage regulation and the output voltage will drop. The
“PSM STATUS” LED will, however, remain illuminated, but dimmed. The unit will
reset automatically as soon as the overload condition is removed .
INPUT SURGE PROTECTION : The unit is protected against input voltage surges.
