 Power Supply DC Connector Pin Assignments
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
Output Voltage
+12 VDC
+5 VDC
+3.3 VDC

–12 VDC
+5 VFP
1
Outputs will meet and not exceed SELV requirements per electrical standards, for example 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 is in a zero load condition.

NOTE:
The +3.3 VDC output wires (orange) must be 16 AWG. All other output wires must be 18 AWG.
