PFC250 AC-DC Series Data Sheet

REV. DEC 08, 2005 Page 1 of 4 www.power-one.com

The PerFormanCe Power PFC250 Series combines Power Factor Correction (PFC) with wide-range outputs to meet

the requirements of data communications and industrial controls. The PFC250-4530 and PFC250-4350 provide high

current +3.3V and +5V on a single platform to support mixed-mode, high-speed digital circuitry.

Power-One’s unique dual-converter architecture combines high reliability with exceptional regulation. All models

feature remote sense on outputs V1 and V2 to provide independent compensation of output cable losses. Other

standard features include independent current sharing on V1 and V2, thermal shutdown, and remote inhibit. Airflow of

300 linear feet per minute (LFM) is required to deliver the full power density of 3.0 watts per cubic inch. The

PerFormanCe Power PFC250 meets international safety requirement s and is CE Marked to the Low Voltage Directive.
