Output
Maximum power Adjustment range Standby output Fan output Hold-up time Overload protection 200W convection; 350 W with 30 CFM forced air 5% 5 V @ 2A regulated, 5% 12 V @ 1A, -5 %, +7%, 0.5A for -CF version 20 ms @ 350 W load, 115 VAC nominal line at factory voltage setting Short circuit protection on all outputs. Case overload protected @ 115-130% above peak rating 20% to 35% above nominal output
Overvoltage protection
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 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.
Remote on/off
