above peak rating
5 V output: 5.7-6.7 VDC.
Logic Control
Power failure
TTL 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
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
Safety
connected. Reverse connection
protected.
