A Division of Vicor
Westcor, a division of Vicor located in Sunnyvale, California, designs and builds medium to high power configurable power supplies that incorporate Vicor DC-DC converters and accessory components. Configurable power solutions come in thousands of variations to satisfy diverse requirements in a wide range of applications. Because each individual power supply is based on a standard, modular design, any model variation is quickly available and provides the competitive advantage of field-proven technology.
FlatPAC-EN
Small, versatile and flexible, the FlatPAC-EN can be configured with all standard VI-200/VI-J00 and Maxi, Mini and Micro DC-DC converters - full, half and quarter-brick sizes. These modules cover the entire range of outputs from 1 to 100 Vdc and 25 to 500 watts, as well as an array of non-standard voltages.
LoPAC Family – AC-DC Switcher Power Supplies
The LoPAC family consists of three ultra low profile, fan cooled, switching power supplies that combine the advantages of power factor correction (PFC) with high power density. They consist of the PFC Mini, PFC Micro and PFC MicroS.
MegaPAC Family – 1-20 Outputs
The MegaPAC family consists of eight, fan-cooled, configurable power supplies that enables users to factory configure almost any set of output requirements by combining appropriate slide-in output assemblies called ConverterPACs, with the appropriate chassis.

ConverterPACs
ConverterPACs are the family of slide-in output assemblies used in MegaPAC power supplies. They can be added, moved, or changed as necessary.
PFC FrontEnd – 375 V Output
The PFC FrontEnd is a low-profile, 1 RU enclosed chassis-mount AC front end that may be used with any 375 Vin Vicor module, VIPAC Array, or other module to create a complete, high-density AC-DC power supply.
