Logic Control
Power fail
TTL Logic signal goes high 50-150 msec after 5 V output. It goes low at least 4 ms before loss of regulation
Remote on/off Requires an external contact (N.O or N.C) to inhibit outputs
DC-OK TTL logic goes high 50-150 msec after the output. It goes low when there is loss of regulation.
Remote sense Compensates for 0.5 V lead drop minimum, will operate without remote sense connected. Reverse
connection protected
