FlatPAC-EN™ and FlatPAC-EN MI
EN Compliant Autoranging Switcher
Overview
The FlatPAC-EN/EN MI is an ultra low profile switching power supply that provides up to 500 Watts from up to 4
isolated outputs. It operates on either 115 or 230 Vac nominal (47-63 Hz), or 250-380 Vdc. It can be populated
with either VI-200/VI-J00 or Maxi/Mini/Micro Vicor converters. The use of these converters gives the FlatPAC-
EN/EN MI the inherent power flexibility typical of all Vicor products. With dimensions of 1.4" H (35,6mm) x 5.0"
W (127mm) x 9.2" L (233,7mm), the FlatPAC-EN/EN MI provides a power density greater than 7W/in
3.
It is facto-
ry configured to meet user output requirements. Note: The FlatPAC-EN/EN MI does not have an internal fan.
The MI version is a rugged chassis designed specifically for COTS and harsh environment applications
Using the PowerBench configurator tool available on vicorpower.com, anybody can now configure a FlatPAC-EN
(and other Westcor power supplies) online.

This feature is implemented in all converter slots (except with Micro modules). Autosense allows automatic local sensing
when remote sense connections are not made. The FlatPAC-EN/EN MI will operate in remote sense mode when remote
sense connections are made. Refer to page 16 for more information on Autosense.
