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.

Output Voltage1	Minimum Current (A)	Maximum Current (A)2
+12 VDC	0.0	16.03
+5 VDC	1.0/0.24	22.0
+3.3 VDC	0.1/0.05	18.0
-	-	-
–12 VDC	0.0	1.0
+5 VFP	0.0	2.0

1Outputs will meet and not exceed SELV requirements per electrical standards, i.e. UL 60950, IEC 60950, EN60950 PAR.2.3.

2Maximum continuous combined load on +5 VDC and +3.3 VDC outputs will not exceed 150 watts.

3Peak +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.

5In system applications where +3.3VDC is not used, all other outputs will stay within regulation while the +3.3 VDC output
