1. Purpose

This specification defines the performance characteristics and functions of a 950 watts redundant power

supply with Active PFC (Power Factor Correction) and hot swappable capabilities.

2. AC Input Requirements

2.1 Input Voltage and Frequency

Voltage (sinusoidal) : 100~240 VAC full range, with 10% tolerance. Input frequency ranges from

47hz~63hz

2.2 AC Input Current and 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 100% of rated load shall be ≥ 0.95 at nominal input voltage.

2.4 AC Line Transient Specification

AC line transient conditions are characterized as “sag” and “surge” conditions. Sag conditions (also referred

to as “brownout” conditions) will be defined as the AC line voltage dropping below nominal voltage. Surge

conditions will be defined as the AC line voltage rising above nominal voltage.

The power supply shall meet

the regulation requirements under the following AC line sage and surge conditions.
