PFC MicroS™
Power Factor Corrected AC-DC Switcher
Overview
The PFC MicroS is an ultra low profile switching power supply that combines the advantages of power factor cor-
rection (PFC) with high power density. This guide covers both the standard and rugged COTS (MI) versions of the
supply. The PFC MicroS provides up to 3 isolated outputs (from 1 slot) and accommodates the following Vicor
DC - DC Converters:
VI-200/VI-J00: 1 full brick or 2 half brick
Maxi/Mini/Micro: 1 full brick, 2 half bricks or 3 quarter bricks
The use of these converters give the PFC MicroS 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 MicroS can provide up to 600 Watts
in a package size of 1.86" H (47.mm) x 5.06" W (128,5mm) x 7.95" L (201,9mm). The PFC MicroS is factory con-
figured to meet output requirements of the user. Using the VSPOC configurator tool available on vicorpower.com,
anybody can now configure a PFC MicroS (and other Westcor power supplies) online.
