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

. 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.

Derates to 260W@90Vac, 400W @ 180 Vac.
2
For output power ≤ 425W, not to exceed an input current of 3.33 A rms at 230 Vac, 50 Hz.
3 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.
Optional Features
• Current Share Board for unit to unit power sharing - See page 26 and page 27
• Connector kits (# 19-130044)
• Conformal coating available on select MI models - contact factory
• -40oC Operation, Mil-STD 810 Shock and Vibration (MI rugged chassis only)
