Description

The Bel S7BA-03E1Ax modules are a series of non-isolated DC/DC converters that deliver up to 3A of output

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

programmable via external resistor from 0.75V to 5.0V 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 and over current protection.
