The ARM is available in Thermal capacity 48 Watt-sec/C either 500/750W or 750/1500W models in a quarter-brick package measuring only 2.28x1.45x0.5in. Part Numbering The ARM interfaces directly with worldwide AC mains and may be used with Vicor 300V input VI-ARM - C 1 2 3 DC-DC converters to realize an autoranging, high-density, low-profile switching power VI-ARMB - C 2 1 supply. The ARM includes a microcontroller that continuously monitors the AC line to Product control bridge/doubler operation. The user need only provide external capacitance to satisfy system hold-up requirements.
