Description
The Bel V7BA-03A1Ax 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 5.5V 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, over-temperature protection, over current
protection, short circuit protection, and undervoltage lockout.
