Remote sense
DC - OK
TTL logic signal goes high 100 - 500 msec after V1 output; It
goes low at least 4 msec before loss of regulation
Requires contact closure to inhibit outputs
Compensates for 0.5 V lead drop min. Will operate without
remote sense connected. Reverse connection protected.
TTL logic signal goes high after main output is in regulation. It
goes low when there is a loss of regulation.
