Logic Control
Power failure:
Remote on/off:
DC OK:
Remote sense:
TTL logic signal goes high 100 - 500 msec after main output. It goes
low at least 4 msec before loss of regulation
Requires an external contact closure to inhibit outputs
TTL logic goes high after the output is in regulation. It goes low when
there is loss of regulation.
Compensates for 0.5 V lead drop min. Will operate without remote
sense connected. Reverse connection protected.
