Presented as providing the industry's highest efficiency at up to 96% from a standard DOSA-compliant quarter-brick package, the RBQ series of isolated 12Vout, 400 Watt DC-DC converters from Murata Power Solutions is well-suited for telecom applications. The RBQ-12/33-D48 is designed to operate in most applications with convection cooling. The RBQ-12/33-D48 can operate from a standard telephone network voltage (TNV) network supply of 36 to 75 VDC around a nominal 48 VDC. The RBQ series is ideal for use in a host of telecommunications, enterprise IT and wireless networking infrastructures that use a distributed power or regulated intermediate bus architecture. The RBQ-12/33-D48 will reliably deliver 33A/400W @ 60°C with 200LFM airflow. Optional features include a load sharing option for higher power or N+1 applications, conformal coating for harsh environments, Positive & Negative on/off control logic and optional pin lengths to accommodate various application board thicknesses. 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. Samples available from stock to 4 weeks, and OEM pricing as low as $44.00, depending on the model. Murata
