Description
The Bel SRBC-10Axx0 modules are a series of non-isolated dc/dc converters that deliver up to 10 A of output current with full load efficiency of 93% at 3.3 Vdc output. The open-frame construction and small footprint enable designers to develop cost and space-efficient solutions. Standard features include remote On/Off, over current protection, short current protection, and wide input. Part Selection Output Voltage Input Voltage Max. Output Current Max.
