Product Overview
These "VIC-in-a-Brick" Intermediate Bus
Converter (IBC) modules use Vicor鈥檚
V鈥 Chip Bus Converter Modules (BCM)
to achieve the highest performance for
Intermediate Bus Architecture applications.
Operating from a 38-55 Vdc input, ten
different fixed ratio outputs are available
from 3 to 48 Vdc. You can choose the
intermediate bus voltage that is optimal for
your system and load requirements.
These quarter-bricks are available with a
single BCM, rated up to 300 W or 70 A, or
with dual BCMs, capable of 600 W or 100 A.
Dual output pins are used for output
currents over 50 A.
Utilizing breakthrough Sine Amplitude
Converter (SAC) technology, BCMs offer
the highest efficiency, lowest noise, fastest
transient response and highest power
density. And full load power is available at
55潞C with only 200 LFM of air for single
BCM versions and 400 LFM for dual BCM
versions, without a heatsink.
