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.
