Short circuit protection on all outputs.
Case overload protected @ 110-145%
above peak rating
5 V output: 5.7-6.7 VDC.
TTL logic signal goes high 50-150 msec
after 5V output. It goes low at least 4
msec before loss of regulation
Requires an external contact (N.O or
N.C) to inhibit outputs
TTL logic goes high 50-150 msec after 5
V output. It goes low when there is loss
of regulation.
Compensates for 0.5 V lead drop min.
Will operate without remote sense
connected. Reverse connection
protected.
