PFC Micro™
Power Factor Corrected AC-DC Switcher
Overview
The PFC Micro is an 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 6 isolated outputs (from 2 slots) and each slot accommodates the following Vicor DC -
DC Converters:
VI-200/VI-J00: 2 VI-200 or 4 VI-J00
Maxi/Mini/Micro Series: 2 Maxis, 4 Minis or 6 Micros.
The use of these converters gives the PFC Micro the inherent power flexibility typical of all Vicor products.
Accepting input voltages of 85 Vac to 264 Vac, and 100 to 300 Vdc, the PFC Micro can provide up to 800 Watts in
a package size of 1.86" H (47.3mm) x 5.06" W (128,5mm) x 10.40" L (264,1mm). The PFC Micro is factory con-
figured to meet user output requirements. Using the PowerBench configurator tool available on vicorpower.com,
anybody can now configure a PFC Micro (and other Westcor power supplies) online.
