Description

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 850 W, 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.
