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.

Vicor 2nd Generation 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.
