Case overload protected @ 115-130% above peak rating 20% to 35% above nominal output Logic Control Power failure Remote on/off Environmental <0.5 mA @ 50/60 Hz, 264 VAC input DC OK Remote sense TTL logic signal goes high 100-500 msec after main output. It goes low at least 4 msec before loss of regulation Requires an external contact closure to inhibit outputs TTL logic goes high after the output is in regulation. 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.
