The Brick Business Unit of Vicor has announced the introduction of the PFC FlatPAC, its new flexible, power dense power supply. The PFC FlatPAC uses Vicor's field-proven VI-HAM and Maxi DC-DC converters to deliver up to 575W of clean, reliable power. It is a single-output power supply available with standard output voltages from 2 to 54 Vdc.

It operates from an input of 85-264 Vac, includes active power factor correction (0.99 power factor), and meets EN61000-3-2 harmonic current limits. Internal filtering provides compliance to EN55022-A conducted EMI. It is available in Vicor’s ultra low profile 34.8 mm FlatPAC chassis, in either finned or conduction-cooled (CC) versions.

Measuring 126 x 235 x 35mm, the universal input, RoHS-compliant AC-DC switcher has a power density greater than 9 W/in3 with up to 90% efficiency
