Logic Control
Power failure T TL logic signal goes high 50-150 msec
after 5 V 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 T TL 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.
