Vicor Corporation PFM AC-DC front-end modules

Vicor Corporation has announced an addition to its family of high-density PFM AC-DC front-end modules in a rugged VIA package that offers good cooling performance and versatility in converter mounting. Featuring a universal AC input range (85–264 VAC), power factor correction and a fully isolated 24 or 48 VDC output, and delivering 400 W of isolated, regulated, DC output power at efficiencies up to 93%, the modules provide a power density of 8 W/cm³ and high performance in a diminutive, 9 mm-thin VIA package. The units are suitable for use in a range of industrial, process control, telecommunications, office equipment, test and measurement, LED lighting and other offline applications.

The units integrate a full range of front-end functions required by contemporary AC line-operated power systems — transient and inrush current protection; input power factor correction; input to output isolation; and a regulated SELV (Safety Extra Low Voltage) DC output — and meet international safety and regulatory agency standards for isolation, conducted emissions, power factor correction, and susceptibility to AC line transients, flicker, interruptions and surges. VIA package configurations are available for both onboard mounting and chassis mounting and units are available in two operating temperature ranges.
