Description
The Bel SRBA-06A1Ax modules are a series of non-isolated dc/dc converters that deliver up to 6 A of output
current with full load efficiency of 92% at 5.0 V output. These modules pro Vide 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.
