Description
The Bel VRBA-06A1Ax modules are a series of non-isolated dc/dc converters that can deliver up to 6 A of
output current with full load efficiency of 92% at 6.0 V output. These modules provide precisely regulated
voltage programmable via external resistor from 0.75 V to 6.0 V over input voltage (10 V-14 V). 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.
