1.0 GENERAL REQUIREMENTS
This specification describes a 350 watts power supply. With +5V stand-by, second
12V rail and remote ON/OFF control for ATX-12V system and a “Power factor
collector (PFC)” circuit to meet EPA requirement of input range with in 230V/50Hz.
The power supply load condition meet ATX 12V v2.3
2.0 INPUT REQUIREMENTS
The AC mains steady-state input voltage shall be 200 to 240 Vrms
The power supply shall operate from 180 to 264 Vrms.
The power supply shall operate from an AC mains frequency of 47-63Hz.
The AC mains steady-state RMS input current shall be:
2.5 Amp (maximum) at 230 Vrms/ 50 Hz.

(1) +3.3V & +5V total output not exceed 103W.
When +5V is load to 15A, the +3.3V maximum load is 8.48A.
When +3.3V is load to 21A, the +5V maximum load is 6.74A.
(2) +12V1 & +12V2 total output not exceed 300W
(3) All outputs shall be safety-isolated from the AC mains and share a common
return. This common return must be connected to supply chassis.
(4) Voltages and ripple are measured at the load side of mating connectors with a
0.1uF monolithic ceramic capacitor paralleled by a 10uF electrolytic capacitor
across the measuring terminals.
