Logic Control
Power failure
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.
Remote on/off
DC OK
