Description
The 0RH1-T5T28x is isolated dc/dc converter that operates from a nominal 48 Vdc source. The unit will provide
up to 350 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 half- brick package.

Output Trim Equations
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 (+). Only one of the resistors should be used for any given application.
Minimum trim down voltage is 22.4V
Maximum trim up voltage is 30.8V.
The total voltage increased by trim and remote sense should not exceed 10% of the nominal output voltage.
