The RBQ series of isolated 12-Vout, 400-W dc/dc converters up to 96% efficiency in a standard DOSA-compliant quarter-brick package. The converter series suits telecommunications, enterprise IT and wireless networking infrastructures that use a distributed power or regulated intermediate bus architecture. It is designed to operate in most applications with convection cooling.

The RBQ-12/33-D48 dc/dc converter operates from a standard telephone network voltage (TNV) network supply of 36 to 75 Vdc around a nominal 48 Vdc. The converters deliver 33 A/400 W at 60°C with 200-lfm airflow. Protection features include output over voltage, over current protection, input under voltage and over temperature shutdown. Input / Output isolation is provided by 2,250 VDC Basic insulation. (Contact company for price and availability.)
