Power Supply DC Connector Pin Assignments
DC Power Connector P1
+5 VDC +/–5% 1.0/0.2 4 22.0
+3.3 VDC +/–5% 0.1/0.0 5 18.0
– 12 VDC +/–10% 0.0 1.0
+5 VFP +/–5% 0.0 2.0
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 150 W.
3 Peak +12 VDC output power (up to 15.0 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.
