forced air
Adjustment range 1.8V - 3.5V; 3.0V - 5.5V on outputs
one and two
Hold-up time 20 ms @ 165 W load
Overload protection Short circuit protection on all outputs.
Case overload protected @ 110-145%
above peak rating. Latching type
recycle AC to reset.
Overvoltage protection Tracks outputs 1 & 2: 20% to 35%
above output setting
Standby output 5V@ 2 A regulated ±5%
Logic Control
Power failure TTL logic signal goes high 100-500
msec after V1 output; it goes low at
least 4 msec before loss of regulation
Remote Inhibit Requires contact closure to inhibit
outputs
Remote sense Compensates for 0.5 V lead drop
minimum, will operate without
remote sense connected. Reverse
connection protection.
DC O TTL logic signal goes high after main
output is in regulation. It goes low
when there is a loss of regulation.
