Value Proposition
Board mount
With the accelerating growth of renewable power, power
engineers now recognized the significant benefits of DC
distribution in large scale power systems. The industry is
responding quickly with an new industry standards and an
expanded portfolio of DC products. The High Voltage
VIA BCM provides a critical function within this new
DC power eco-system by providing 380 V to 48 V bus
conversion in an ultra-small, efficient, and easy-to-use
power component.

Small Size, low profile
Product Description
Eliminates constraints of size and height in a design
The High Voltage VIA BCM is a highly advanced 1.75 kW bus
converter operating from a 260 V to 410 VDC input which
delivers an isolated Safety Extra Low Voltage (SELV) 48 V
secondary output. This unique, ultra-low profile module
incorporates bus conversion, integrated filtering and transient
surge protection in chassis mount or PCB mount form
factor. The High Voltage VIA BCM enables a versatile two
sided thermal strategy which greatly simplifies the thermal
design of such a high density device. When combined with
downstream Vicor DC-DC conversion products and regulators,
the High Voltage VIA BCM allows the power design engineer
to achieve industry benchmark power density and electrical
performance with a small, easy-to-use power component.
