Logical Control
Power failure 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
