Vicor Corp. has announced its Westcor MicroPAC power factor corrected AC/DC power system that according to the company gives up to 1.3kW of continuous power at up to 92 percent efficiency and 25Win3 power density in a 4 x 1.72 x 7.45in package. Offering semi-regulated output voltages of 12, 24, 36 and 48VDC via four factory-configurable isolated outputs, the devices are aimed at distributed power architectures in industrial and automation, MIL-COTS, telecom and renewable energy applications, added the company.

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, noted Vicor. During standby-mode, total power dissipation (TPD) is less than 8W, which is exceptional for a power system rated up to 1.3kW, the company indicated.

MicroPACs operate at full load from -40C to 55C and are ruggedized for harsh environments. As an alternative to competing MIL-class power systems, MicroPACs meet MIL-STD 810 standards for shock and vibrationup to 7Gs per axis for one hour each, and 40G functional shockand are therefore well suited for ground vehicle, aircraft and ship transport and usage.

The MicroPAC configurable power system is priced as low as $420.00 for industrial quantities.
