New conduction cooled Westcor MicroPAC power system from Vicor

Vicor has introduced a new conduction-cooled version of its highly efficient Westcor MicroPAC power factor corrected AC-DC power system, enabling system designers to forego fan and forced-air cooling in power systems designed for demanding military, industrial, telecommunications and other applications requiring fanless and/or noiseless operation in restrictive enclosures.

The new conduction-cooled MicroPAC power systems incorporate VI Chip BCM bus converters and are suited for distributed power architectures, providing up to 1300 W of continuous power at up to 92% efficiency and 25 Win3 power density in a compact 101,6 x 43,7 x 189,2 mm package.

Supporting the universal AC input range (85 – 264 Vac) and offering semi-regulated output voltages of 12, 14, 24, 28, 36 and 48 Vdc via four factory-configurable isolated outputs, the new conduction cooled Westcor MicroPACs satisfy a wide range of customer power requirements. These systems also feature optional eco-mode operation settings via which the individual outputs are powered on only as needed, further enhancing overall power efficiency.

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 BCM high-voltage bus converters, which may be factory 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 up to several kW with box-to-box current sharing.

The MicroPAC conduction-cooled power system has a base plate operational temperature range from -40°C to +65°C. The power supply lid (base plate) is designed to attach to heat-sinking surfaces, eliminating the need for fans or forced air cooling and enabling system designers to employ sealed enclosures to protect against moisture and particulate ingress.

“The new conduction-cooled Westcor MicroPAC configurable power systems give designers greater flexibility to ruggedize their systems for challenging conditions,” said Jeff Lally, Westcor product manager. “This helps to enhance overall system integrity and lower noise output in demanding environments.”
