Product Highlights
The ARM (Autoranging Rectifier Module) is an AC front end module which provides autoranging line rectification and inrush current limiting. The ARM is available in either 500/750W or 750/1000W models in a mini sized package measuring only 2.28" x 1.45" x 0.5".
The ARM interfaces directly with worldwide AC mains and may be used with Vicor 1st or 2nd Generation 300V input DC-DC converters to realize an autoranging, high density, low profile switching power supply. The ARM 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.
Actual size: 2.28 x 1.45 x 0.5 in

Electrical Characteristics
Electrical characteristics apply over the full operating range of input voltage, output load (resistive) and baseplate temperature, unless otherwise specified. All temperatures refer to the operating temperature at the center of the baseplate. Specifications apply for AC mains having up to 5% total harmonic distortion.
