SPECIFICATION

1. GENERAL REQUIREMENTS

2. INPUT REQUIREMENTS

This specification describes a 400 watts power supply. With+ 5V stand-by , remote

ON/OFF control for ATX system and passive PFC(Power Factor Correction) (option)

circuit at 230 Vac.

The power supply shall operate in 115Vrms±10% or 230Vrms ±10%. The power

supply shall operate from an AC mains frequency of 47 through 63 Hz. Maximum

inrush current from power-on (with power on at any point on the AC sine) and

including, but not limited to, three line cycles, shall be limited to a level below the

surge rating of the input line cord, AC switch if present, bridge rectifier, fuse, and EMI

filter components. Repetitive ON/OFF cycling of the AC input voltage should not

damage the power supply or cause the input fuse to blow.

The AC mains steady-state RMS input current shall be:

8.5 amps maximum / 115 Vrms, 60 Hz.

5 amps maximum / 230 Vrms, 50 Hz.

3.5.3 Short-Current Protection

A short circuit at any output shall cause no damage to the power supply nor blow the primary fuse. The supply may shut down in the event of a short circuit and require power-on restart. A short circuit consists of application of a test resistance of less than 0.05 ohms at each output with maximum load on all outputs.

3.6 OUTPUT RISETIME

The cold-start enable output voltage risetime of all outputs shall be measured with maximum load on all outputs.

risetime : +3.3V 20mS (maximum)
