VI Brick® Intermediate Bus Converter

Open frame intermediate bus converter

This product is not recommended for new designs. Please use the Power System Designer tool to find a product for your project.

These Intermediate Bus Converter (IBC) modules are very efficient, low-profile, isolated, fixed-ratio converters for power system applications in enterprise and optical access networks. Rated at up to 850W, these IBCs conform to industry-standard eighth- and quarter-brick footprints. The greatly increased power capability often allows the eighth brick to replace a conventional quarter brick, while the quarter bricks can replace two or more conventional quarter bricks. Their leading efficiency enables full-power operation at 65°C with as little as 400LFM airflow. Their small cross section facilitates unimpeded airflow — above and below the thin body — to minimize the temperature rise of downstream components.
