... In addition to providing transient/surge immunity and EMI filtering, the FARM contains all of the power switching and control circuitry necessary for autoranging rectification, inrush current limiting, and overvoltage protection. This module also provides converter enable and status functions for orderly power up/down control or sequencing ...

... FARM1xxx is rated at 500W in the low range (90-132Vac input), and 750W in the high range (180-264Vac input). The FARM2xxx is rated for 750W and 1000W for the low and high input ranges respectively. Either of these modules can serve as the AC front end for any number and combination of compatible converters as long as the maximum power rating is not exceeded ...

... Example In this example, the output required from the DC-DC converter at the point of load is 12Vdc at 320W. Therefore, the output power from the FARM would be 375W (assuming a converter efficiency of 85%). The desired hold-up time over an input range 264Vac. Determining Required Capacitance for Power Fail Warning ...
