PRODUCTION INFORMATION
The FARM (Filter/Autoranging Rectifier Module) is an AC front which provides EMI filtering, autoranging line rectification, transient protection and
inrush current limiting. The FARM is available in either 500/750W or 750/1000W models in a mini sized package measuring only 57.9x55.9x12.7mm.
The FARM interfaces directly with worldwide AC mains and may be used with Vicor 300 V 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.
