The 250-W power supply can operate from an AC power source of 115 VAC or 230 VAC at 50 – 60 Hz. The power supply
provides the DC operating voltages and currents listed in the following table.

1
Outputs will meet and not exceed SELV requirements per electrical standards, i.e. UL 60950, IEC 60950, EN60950
PAR.2.3.
2
Maximum continuous combined load on +5 VDC and +3.3 VDC outputs will not exceed 150 watts.
3
Peak +12 VDC output power (up to 17.0 amps) will not exceed 15 seconds in duration. Under this condition, tolerance on
the +12v output, is allowed to be +/- 10%.
4
+5 VDC minimum load will be 0.2A when there is a minimum load of 0.3A on the +12 VDC and 0.42A on the +3.3 VDC
outputs simultaneously. +5V min load is 1A for load transient tests.
5
In system applications where +3.3VDC is not used, all other outputs will stay within regulation while the +3.3 VDC output
