Power Supply

The 145-W power supply can operate from an AC power source of 115 VAC at 60 Hz or 230 VAC at 50 Hz. The power supply provides the DC operating voltages and currents listed in the following table.

Output Voltage1	Regulation	Minimum Current (A)	Maximum Current (A)2
+12 VDC	+/–5%	0.0	4.5
+5 VDC	+/–5%	1.0	16.0
+3.3 VDC	+/–5%	0.1/0.03	10.0
–5 VDC	+/–10%	0.0	0.3
–12 VDC	+/–10%	0.0	0.3
+5 VFP	+/–5%	0.0	1.2
1Outputs meet and do not exceed SELV requirements per electrical standards (UL 1950, IEC 950, or EN60950 Par. 2.3). 2Maximum continuous combined load on +5 VDC and +3.3 VDC outputs do not exceed 85 W. 3In system configurations where +3.3 VDC is not used, all other outputs stay within regulation while the +3.3 VDC output is in a zero load condition.
