Vicor has announced the release of its new Westcor MicroPAC power factor corrected AC-DC power system providing up to 1300 W of continuous power at up to 92% efficiency and 1.53 W/cm3 power density in a compact 102x44x190 mm package.

Offering semi-regulated output voltages of 12, 24, 36 and 48 VDC via four factory-configurable isolated outputs, the new Westcor MicroPACs support a wide range of customer power requirements and are ideally suited for distributed power architectures in industrial and automation, MIL-COTS, telecom and renewable energy applications.

System designers seeking the flexibility to partition multiple voltage outputs rather than use two separate power supplies can configure MicroPACs with a combination of four high performance VI Chip BCM high-voltage bus converters, which may be configured as single outputs, parallel outputs, or a series output with integrated current sharing. For applications requiring higher power levels, MicroPACs can be configured in arrays with box-to-box current sharing.

Energy Star-compliant MicroPACs offer advanced eco-mode operation settings via which the individual BCMs are powered on only as needed, further enhancing power efficiency over a wide load range. During standby-mode, total power dissipation is less than 8 W, which is exceptional for a power supply rated up to 1300 W.

MicroPACs operate at full load over a wide temperature range (-40 to +55C) and are ruggedized for harsh environments. Offering an economical alternative to competing MIL-class power systems, MicroPACs meet MIL-STD 810 standards for shock and vibration – up to 7Gs per axis for one hour each, and 40G functional shock – and are therefore well suited for ground vehicle, aircraft and ship transport and usage.

“The Westcor MicroPAC configurable power systems strikes an ideal balance of power density, efficiency and design flexibility, while offering advanced power-saving capabilities that minimize system-level power consumption,” said Jeff Lally, Westcor product manager. “Ensuring high efficiency operation over a wide power range with high-calibre ruggedization, MicroPACs
