UL leakage safety specification limit
(0 to 100% load, -10 to 65°C)
Input Current: (Maximum Load At
25°C with Nominal Output Voltage)

Input Protection
A limiting resistor in series with a resistor fuse (and thyristor circuit) reduces start-up surge.
Units are protected against shorts by an input fuse. Fuse value 25.0A At 250 Volts

200V a-c
Overvoltage Protection
When the Power Supply goes into an overvoltage condition, the output is cut OFF. To restart
(reset) the unit, it is necessary to remove the a-c input power, wait approximately 30 seconds,
and then reconnect the a-c input power. An alternative is to open and then reclose the RC ter-
minals (no waiting time required).
Low Output Voltage Protection
If output falls to 60% of rated output (5V for 36V model) for approximately 30 Seconds and
overcurrent is triggered, the output is cut OFF. To restart (reset) the unit, it is necessary to
remove the a-c input power, wait approximately 30 seconds, and then reconnect the a-c input
power. An alternative is to open and then reclose the RC terminals (no waiting time required).
Remote Control ON/OFF:
"High", 2.4V to 24V (or open), unit OFF- Fan Off ; "Low", 0.0V to 0.4V (or closed), unit ON.
Source current is 1.6mA maximum at low level, and sink current is 1.0 mA maximum at high
level. The ±RC terminals are isolated from the a-c input terminal and the DC output terminals.
When remote ON/OFF is not in use, ±RC terminals must be shorted (use shorting link sup-
plied) for unit to operate.
Operating Temperature:
-10 to 65°C
Startup Temperature
-20 to -10°C
Storage Temperature:
-30°C to +75°C
