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 Vdc output. These modules provide precisely regulated voltage

programmable via external resistor from 0.75 Vdc to 6.0 Vdc over input voltage (10 Vdc - 14 Vdc). 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.
