Logic Control
Power failure
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
