4. OUTPUT ELECTRICAL REQUIREMENTS

4.1. OUTPUT VOLTAGE AND CURRENT RATING

( 1 ) +3.3V & +5V total output not exceed 110W.

( 2 ) Total output continuous shall not exceed 300W.

( 3 ) +12V2 peak current is 19A (less then 10m Sec.) , minimum voltage during peak is >10.8Vdc.

( 4 ) 5Vsb peak current is 2.5A(less then 500m Sec.) , minimum voltage during peak is >4.5Vdc.

( 5 )Voltages and ripple are measured at the load side of mating connectors with a 0.1 uF monolithic

ceramic capacitor paralleled by a 10 uF electrolytic capacitor across the measuring terminals.
