Overvoltage Protection When the Power Supply goes into an overvoltage condition, the output is cut OFF. See PAR.
3.7.1.
Remote Control ON/OFF: ±RC pins control on/off as follows:
“High”, 2.4V to 24V (or open), unit OFF- Fan Off;
“Low”, 0.0V to 0.4V (or closed), unit ON.
Source current: 1.6mA maximum at low level
Sink current: 1.0 mA maximum at high level. Must be enabled by DIP switch positions 3
and 4 (see PAR. 3.4.3).
Meter (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%
Operating Temperature: -10 to 40°C (see Figure 2.)
Startup Temperature -10 to -20°C (see Figure 2.)
Storage Temperature: -30°C to +75°C
