Description
The XRP2-40E1AC is a non-isolated dc/dc converter that operates over a wide range of input voltage (Vin = 5 Vdc - 13.8 Vdc). This unit can provide a precisely regulated output voltage from 0.6 Vdc to 5.0 Vdc and can deliver up to 40 A of output current. This unit is designed to be highly efficient and low cost. The converter is provided in an industry standard package.
