Description
The 0RLC-25T series are isolated dc/dc converters that operate from a nominal 48 Vdc source. These units will
provide up to 30 W of output power. These units are designed to be high efficient and very low cost. Features
include remote on/off, over current protection, and under voltage lockout. These converters are provided in an
industry standard package.

Output Trim Equations
Equations for calculating the trim resistor (in kΩ) given the desired adjusted voltage (Vadj) and the nominal
output voltage of the converter (Vnom) are shown below. The Trim Down resistor should be connected between
the Trim pin and Vout. The Trim Up resistor should be connected between the Trim pin and Ground. Only one of
the resistors should be used for any given application.
