Description
The Bel VRBA-06E1Ax 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 5.0 Vdc output. These modules provide precisely regulated voltage
programmable via external resistor from 0.75 Vdc to 5.0 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 and over current protection.
