Overvoltage Protection
When the Power Supply goes into an overvoltage condition, the output is cut OFF. See PAR.
3.6.1.
Remote Control ON/OFF:
±RC pins control on/off as follows:
“High”, 2.4V to 12V (or open), unit OFF- Fan
Off;
“Low”, 0.0V to 0.8V (or shorted), unit ON.
Source current: 1.6mA maximum at low level
Sink current: 3.5 mA maximum at high level.
Must be enabled by DIP switch positions 3
and 4 (see PAR. 3.5).
Meter (AM Models only) (displays
voltage or current; front panel
switch-selectable)
Voltmeter Accuracy: ±3%
Ammeter Accuracy: ±5% for loads between
10%-100%
Voltmeter reads sense lines; use remote
sensing to display voltage at load.
Ammeter accuracy degrades significantly for
loads less than 10%
