ATX12V 2.3 Switching Power Supply

With Active PFC

PS/2 450W

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

PS/2 Fanless Switching power supply; the maximum output shall be 450W when Input

Voltage is from 100V to 240V. This power supply is also design with Active PFC

(Power Factor Correction) capabilities.

2.1. AC Input Voltage, Frequency and Current (Rating: 100V-240Vac, 47-63Hz, 6-3A)

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.
