Product Description
The MicroPAC is the first Westcor product to utilize Vicor’s VI Chip technology. The power supply uses
BCM modules to provide up to 4 isolated semi regulated output voltages of 12, 24, 36 and 48 Vdc and
up to 1300 W of continuous power in a very small highly efficient package. The isolated outputs may be placed
in parallel/series configurations and for applications requiring higher power levels MicroPAC
power supplies can be configured in arrays up to several KW.
This factory configurable rugged power supply supports a wide range of customer power requirements and is
especially suited for distributed power architectures. The design offers a small flexible cost effective solution for
applications requiring Power Factor Correction, high efficiency and power density even in environmentally
challenging conditions.
