Minimum
T TL 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
C ompensates 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
