AC/DC module range extended

Vicor has expanded its family of PFM AC/DC front end modules. Supplied in a rugged VIA package, said to offer better cooling performance and versatility in converter mounting, the 400W modules accept an input ranging from 85 to 264V AC and deliver a fully isolated 24V DC or 48V DC output.

With power factor correction and efficiencies of up to 93%, the modules are said to have a power density of 8W/cm3.

Only 9mm thick – 20% that of a traditional 1U package – the modules can be mounted on an equipment side panel, chassis or heat sinking device. Vicor says that moving the AC/DC conversion function to a chassis or side panel can reduce system size and cost, free space for other uses and improve thermal performance.

The units are suited for use in a range of applications, including process control, telecommunications, office equipment, test and measurement and LED lighting.
