SilverStone ST85EF [2/16] St75zf manual 02

1. General

This specification describes the electrical characteristics, functional and physical of a PS/2

750 watts switching power supply with Active PFC (Power Factor Correction) capabilities.

2. AC Input Characteristics

2.1 AC Input Voltage, Frequency and Current ( Rating: 100V-240Vac, 47-63Hz, 12-6A )

The power supply must operate within all specified limits over the input voltage range in Table 1.

Harmonics distortion of up to 10% THD must not cause the power supply to go out of specified limits.

2.2 AC Inrush Current

AC line inrush current shall not damage any component nor cause the AC line fuse to blow

under any DC conditions and with any specified AC line input voltage and frequency. Repetitive

On/Off cycling of the AC input voltage shall not damage the power supply.

2.3 Input Power Factor Correction ( Active PFC)

The power factor at full load shall be

≧

0.95 at nominal input voltage.
