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.
