Description
The 0RFB-S0T280 is an isolated dc/dc converter that operates from a nominal 48 Vdc source. These units will
provide up to 700 W of output power from a nominal 48 Vdc input. This unit is designed to be highly efficient and
low cost. Features include remote on/off, over current protection, input under-voltage and over-voltage lockout.
This converter is provided in an industry standard full brick package.

Output Trim Equations
1. Equations for calculating the trim resistor are shown below. The Trim Down resistor should be connected
between the Trim pin and Sense(-) pin. The Trim Up resistor should be connected between the Trim pin and the
Sense(+) pin. Only one of the resistors should be used for any given application.
