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 500/750 W or 750/1500 W models in a
quarter brick 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
300 V 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.

Vicor Micro series packaging technology
offers flexible mounting options for various
manufacturing processes. The ARM may be
installed as a conventional leaded device for
on-board applications, in-board for low
profile, height restricted applications,
socketed or surface mounted with optional
ModuMate interconnect products.
