Power Supply
The 160-W power supply can operate from an AC power source supplying 90-135 VAC or 180-265 VAC at 47-63 Hz. The power supply provides the DC
operating voltages and currents listed in the following table.

1
Outputs meet and do not exceed SELV requirements per electrical standards (UL 1950, IEC 950, or EN60950 Par. 2.3).
2
Maximum continuous combined load on +5 VDC and +3.3 VDC outputs do not exceed 80 W.
3
Peak +12 VDC output power (up to 11.0 A) does not exceed 15 seconds in duration. Under this condition, tolerance on the +12 VDC output is allowed to
be +–10%.
4
+5 VDC minimum load is 0.2 A when there is a minimum load of 0.3 A on the +12 VDC and 0.42 A on the +3.3 VDC outputs simultaneously. +5 V minimum
load is 1 A for load transient tests.
5
In 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.
