Note:

( 1 )Total combined output load of +3.3V and +5V is ≦100W.

( 2 )+12V Maximum output power should not exceed 360W.

( 3 )When +5V load is over 15A,+12V min load is 2A.

( 4 )When +12V load is over 25A,+5V min load is 4A.

( 5 )Maximum continuous total DC output power should not exceed 400W.

( 6 )Peak DC output power should not exceed 420W for 12 second.

The ripple voltage of the outputs shall be measured at the pins of the output connector The ripple voltage

of the outputs shall be measured at the pins of the output connector at the connectors with a 0.1uF

ceramic capacitor and a 10uF electrolytic capacitor to simulate system loading. Ripple shall be measured

under any condition of line voltage, output load, line frequency, operation temperature.
