Description

The Bel SRBA-03A1Ax modules are a series of non-isolated dc/dc converters that deliver up to 3 A of output

current with full load efficiency of 93% at 5.0 V output. These modules provide precisely regulated voltage

programmable via external resistor from 0.75 V to 5.5 V over a wide range of input voltage. Their open-frame

construction and small footprint enable designers to develop cost and space-efficient solutions. Standard

features include remote On/Off, programmable output voltage, over-temperature protection, over current

protection, short circuit protection, and under-voltage lockout.
