Description

The Bel SRBC-10A1Ax 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 V output. These modules provide precisely regulated voltage

programmable via external resistor from 0.75 V to 5.0 V over a wide range of input voltage (8.3 V - 14 V). 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, wide input, and

programmable output voltage.
