Description
The VRP4-80A1Ax is a non-isolated dc/dc converter that operates from a nominal 12 Vdc source. This unit can
provide a precisely regulated output voltage from 0.6 Vdc to 5.0 Vdc and can deliver up to 80 A of output current.
This unit is designed to be highly efficient and low cost. The converter is provided in an industry standard
package.
