Description
The 0RHB-F5S53x are isolated dc/dc converters that operate from a nominal 48 Vdc source. These units will
provide up to 550 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 lockout, and current share
for parellel working. 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 Ground pin. The Trim Up resistor should be connected between the Trim pin and the
Vout. Only one of the resistors should be used for any given application.
