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 Vdc output. These modules provide precisely regulated voltage

programmable via external resistor from 0.75 Vdc to 5.5 Vdc 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.
