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, 14, 24, 28, 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. Safety agency approvals limit the configured output voltages to 60Vdc. Configurations and applications where output
voltages are greater than 60Vdc are non-SELV.
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.
