This specification describes the requirements of 450Watts with full range voltage, switching power supply with a reliability SFX-L small form factor standard

1.0 AC INPUT

1.1 AC input requirements

The input voltage, current, and frequency requirements for continuous operation are stated below.

Parameter Min Nom Max Unit

Vin 90 100 -- 240 264 VACrms

Vin Frequency 47 60 -- 50 63 Hz

2.3.2 Definition

The ripple voltage of the outputs shall be measured at the pins of the output connector when terminated in the load impedance specified in figure1.Ripple and noise are measured 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.
