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. 12 VDC/300mA for external fan 1 second mS ±5% PROTECTION CIRCUIT parameter Input fuse overload short circuit output over-voltage over temp. 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. 20050 SW 112th Ave. Tualatin, Oregon 97062 phone 503.612.2300 fax 503.612.2383 www.v-infinity.com rev.
