VI BRICK™ Intermediate Bus Converters

Industry Standard Eighth-Brick Bus Converter up to 500 Watt

Description

The Intermediate Bus Converter (IBC) Modules are a very efficient, low profile, isolated, fixed ratio converters for power system applications in enterprise and optical access networks.

Rated at up to 500 W from 36 Vin and up to 750 W from 54 to 60 Vin, the IBC conforms to an industry standard eighth or quarter-brick footprint while supplying the power of the next size up standard brick. Its leading efficiency enables full load operation at 55°C with only 200 LFM airflow. Its small cross section facilitates unimpeded airflow — above and below its thin body — to minimize the temperature rise of downstream components. Medium power versions are available for cost effective solutions for reduced power requirements.
