• Voltage
range:
85 to 265 VAC; 47 – 63 Hz. via IEC socket;
Rated voltage (for safety approval):
100-240 VAC, 50-60 Hz.
• Current:
Maximum input current at 85 VAC is 16.8
amp for six PSMs
• Power
factor:
>0.925 at maximum load
• Efficiency:
For 100 VAC input voltage: 86% minimum
at 25°C and 85% minimum at 55°C
For 220 VAC input voltage: 88% minimum
at 25°C and 86% minimum at 55°C

2. Verify normal operation for each PSM by monitoring the PSM LEDs.
Each PSM has three LEDs – one power LED (per PSM) and two output LEDs.
LED
Description
Recommended Action
PSM LED Green – power OK -
Red - indicates one (or more) of the
following:
• Insufficient input power
• Problem with output load at one or both
PSM output ports
• PSM over temperature protection set
• Fan failure
-
Off in one PSM – PSM is off
-
Off in all PSMs – no power input detected
Check power source
Output LED 1/2
Off – normal operation -
Red – short circuit or overload detected. Disconnect the load and then re-connect. If
the problem continues the load may be
faulty and may need to be replaced.
