Overtemperature Protection
Power Fail (FAL#)
CONDITIONS/DESCRIPTION
Latch style overvoltage protection.
Fully protected against output overload and short circuit. Automatic recovery upon removal of overload condition.
System shutdown due to excessive internal temperature, automatic reset.
TTL compatible signal, open collector active low signal. Indicates any output below
90% and/or a low input <85VAC.
Accuracy of shared current with up to 6 parallel units. Single wire current share on V1, V2, and V3.
Available on V1, V2, and V3. Total voltage compensation for cable losses with
respect to the main output.
TTL-compatible signal inhibited with GND or TTL "0".
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.
