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 345 W from 36 Vin and up to 500 W from 54 to 60 Vin, the IBC
conforms to an industry standard eighth brick footprint while supplying the power of
a quarter 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.
