Hold-up time
20 ms @ 350 W load, 115 VAC nominal
line at factory voltage setting
Overload protection
Short circuit protection on all outputs.
Case overload protected @ 115-130%
above peak rating
Overvoltage protection
20% to 35% above nominal output
Logic Control
Power failure
TTL logic signal goes high 100-500 msec
after main output. It goes low at least 4
msec before loss of regulation
Remote on/off
Requires an external contact closure to
inhibit outputs
DC OK
TTL logic goes high after the output is in
regulation. 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.
Active power factor correction
