AC power supply:
approx. 85% (230 V AC/120 V AC) with typical load (50%)
and 82% (230 V AC/120 V AC) with full (100%) or light load
(20%)

Note
•
Total output power of +5 V and +3.3 V should be less than 91Watts.
•
DC output power should be less than 350Watts.
•
When AC input below 115 V, DC output power should derate 20% load at 50
℃.
