Logic Control
Power failure TTL logic signal goes high 50-150 msec
after 5V output. It goes low at least 4
msec before loss of regulation
Remote on/off Requires an external contact (N.O or
N.C) to inhibit outputs
DC-OK TTL logic goes high 50-150 msec after 5
V output. 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.
