Product Overview
The Intermediate Bus Converter (IBC) Module is a very efficient, low profile, isolated, fixed
ratio converter for power system applications in enterprise and optical access networks.
Rated at up to 477 W from 36 Vin and up to 650 W from 50 to 60 Vin, the IBC
conforms to an industry standard quarter-brick footprint while supplying power greatly
exceeding competitive quarter-bricks. 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.
