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