Notes:
1 Customer must specify output voltage on PO.
2 Output is fully isolated.
3 Output voltage is measured at output power connector.
4 Provides peak power of 600 W within 500 µS for all models. For longer duty duration please contact us.
5 1% minimum load is required to maintain the ripple and regulation.
6 Ripple and noise is measured from 10 KHz to 20 MHz at output terminals with a 0.1 µF ceramic capacitor and
a 22 µF electrolytic capacitor in parallel.

Designated as RMSW on the CN1. Requires a low signal to inhibit the output.
When green (LED1) is on the power supply is operating normally.
Designated as PG on the CN1. This signal
goes high 100-500 mS after the output reaches regulation.
It goes low at least 1 mS before loss of regulation.
Protection Circuit
Parameter
Input Fuse
Overload
Short circuit
Output Over-voltage
Conditions/Description
Built-in ac fuse. A blown fuse usually indicates permanent
damage to the power supply serviceable by factory only.
Current limiting starts at 110-140% of the rated output current in foldback mode and
recovers automatically.
Short circuit can be continuous. Recovers automatically upon removal of short.
Output is protected agaist overvoltage. Unit shuts down and latches
when voltage at output terminals exceeds 130%. AC input needs to be
reset to restart the power supply.
Power supply shuts down when temperature is in excess of 85 ºC. Auto recovery.
Over temp.
