Overview

The PFC Micro is a low-profile switching power supply that combines the advantages of power factor

correction (PFC) and high power density. This guide covers both standard and rugged COTS (MI)

versions of the supply. A PFC Micro provides up to six isolated outputs (from two slots) and each slot

may accommodate the following Vicor DC-DC Converters:

VE-200™/VE-J00™ Series:

1 VE-200 or 2 VE-J00

Maxi/Mini/ Micro Series:

1 Maxi, 2 Minis, or 3 Micros

The use of these converters gives the PFC Micro the inherent power flexibility typical of all Vicor

products. Accepting input voltages of 85 – 264V

, and 100 – 300V

, the PFC Micro can provide

up to 800W in a package size of 1.86 x 5.06 x 10.40in [47,3 x 128,5 x 264,1mm]. The PFC Micro is

factory-configured to meet user output requirements.
