Product Highlights

The FARM (Filter/Autoranging Rectifier

Module) is an AC front-end module which

provides EMI filtering, autoranging line

rectification and inrush current limiting. The

FARM is available in either 500/750W or

750/1000W models in a mini sized package

measuring only 2.28" x 2.2" x 0.5".

The FARM interfaces directly with

worldwide AC mains and may be used with

Vicor 1st or 2nd Generation 300V input

DC-DC converters to realize an autoranging,

high density, low profile switching power

supply. The FARM includes a microcontroller

that continuously monitors the AC line to

control bridge/doubler operation. The user

need only provide external capacitance to

satisfy system hold-up requirements.

Vicor 2nd Generation packaging technology

offers flexible mounting options for various

manufacturing processes. The FARM may be

installed as a conventional leaded device

for on-board applications, in-board for low

profile, height restricted applications,

socketed or surface mounted with optional

ModuMate interconnect products.
