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 500/750 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 holdup 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.
