The FARM is Baseplate to sink available in either 500/750W or 750/1000W flat, greased surface 0.16 C/Watt models in a mini sized package measuring only with thermal pad (P/N 20264) 0.14 C/Watt 2.28 x 2.2 x 0.5in. Baseplate to ambient Free convection 8.0 C/Watt The FARM interfaces directly with worldwide 1000LFM 1.9 C/Watt AC mains and may be used with Vicor 300V input DC-DC converters to realize an autoranging, high-density, low-profile switching power supply. The FARM includes Part Numbering a microcontroller that continuously monitors the AC line to control bridge / doubler FARM 1 C 1 1 operation.
