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