Thin AC/DC front-end modules deliver up to 48V output

Vicor has rolled out the high density, integrated VIA PFM AC-DC front-end modules that offer PFC regulation and enables 24V or 48V output at up to 400W in a 9mm profile.

The VIA PFM power modules achieve a power density of 8W/cm3 supplying an isolated, PFC regulated 24V or 48V SELV DC output at up to 400W from the universal AC input range of 85 to 264V with 93 per cent peak efficiency.

The VIA PFM is five times thinner than traditional U supplies, offering novel design advantages to power system architects challenged by size constraints. With its 9mm thin profile and 36mm width, the VIA PFM can be mounted on the sidewall of any typical 1U chassis, saving valuable real estate. Thermally adept VIA PFMs may be chassis mounted and conduction cooled to eliminate fans, thereby improving overall system reliability and further minimising the power system footprint. High density, high efficiency and low thermal resistance make VIA PFM front-end modules well suited for a wide range of end-market applications, including small cell wireless base stations, size constrained LED lighting applications, industrial and automation systems.

VIA PFM front-end power modules are available from Vicor and Vicor-authorised distributors. Pricing starts at $107 for OEM quantities.
