Rugged 1300-W Power System Leaks Just 8 W In Standby

74358-AAndover, Mass., U.S.: The Westcor MicroPAC power factor corrected ac-dc power system from Vicor offers up to 1300 W of continuous power at up to 92% efficiency (see the figure). Power density is 1.53 W/cm3 in the device’s 102- by 44- by 190-mm package. Power dissipation is just 8 W in standby mode.

Four factory-configured isolated outputs offer semi-regulated output voltages of 12, 24, 36, and 48 V dc. By configuring a MicroPAC with four of the company’s VI Chip BCM high-voltage bus converters, designers can partition multiple voltage outputs from one power supply. They can be configured as single or parallel outputs or as 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. Eco-mode settings mean the bus converters are switched on only when needed.

MicroPACs operate at full load from –40°C to 55°C and are ruggedized for harsh environments. Offering an economical alternative to competing MIL-class power systems, they meet MIL-STD 810 standards for shock and vibration—up to 7Gs per axis for one hour each and 40G functional shock—suiting ground vehicle, aircraft, and ship transport and usage.
