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.
