Overload Protection
Fully protected against output overload and short circuit. Automatic recovery upon removal of overload condition.
Overtemperature Protection
System shutdown due to excessive internal temperature, automatic reset.
Power Fail (FAL#)
TTL compatible signal, open collector active low signal. Indicates any output below
90% and/or a low input <36VDC.
Current Share
Accuracy of shared current with up to 6 parallel units. Single wire current share on V1, V2, and V3.

Inhibit (INH#)
TTL-compatible signal inhibited with GND or TTL "0".
Enable (EN#)
Contact closure to external ground to start unit. On shortest pin (last make, first break).
Overtemperature Warning (DEG#) Provides warning when power supply temperature exceeds rating. TTL-compatible open.
Front Panel LED Status Indicators Input OK (Green), Output Failure (Red).
