DC Power Connectors
Power Supply DC Connector Pin Assignments
DC Power Connector P1
+5 VDC +/–5% 1.0 22.0
+3.3 VDC +/–5% 0.1/0.0 4 18.0
– 12 VDC +/–10% 0.0 1.0
+5 VFP +/–5% 0.0 2.0
When the current load is outside of the ranges listed, but within each specified output current range, the +5-V, +12-V, and +3.3-V outputs are allowed to
regulate at +/–10% of nominal DC voltages.
1 In system applications where +3.3 VDC is not used, these values may be 0 A
without affecting the regulation on the other outputs.
2 Peak +12-VDC output power (up to 12 A) does not exceed 15 seconds in
duration. In this condition, the tolerance on the +12-V output is allowed to
be +/–10%.
3 The required full load combinations are adjusted so that the total output
power is less than or equal to 250 W.
4 Maximum continuous total DC output cannot exceed 200 W. Maximum
continuous combined load on +5-VDC and +3.3-VDC outputs cannot
exceed 135 W.
