Description

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 500/750 W or 750/1000 W models in a half-brick-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 300 Vin VI-200 / VI-J00 series DC-DC converter or 300 Vin Maxi, Mini and Micro series 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.

Our Maxi, Mini and Micro series packaging technology offers flexible mounting options for various manufacturing processes. The FARM utilizes the mini-size package and may be installed as a conventional leaded device for onboard applications, inboard for low-profile, height-restricted applications, socketed or surface mounted with optional ModuMate interconnect products.
