Description
The 0RQB-D0T28x is isolated dc/dc converter that operates from a nominal 48 Vdc source. This unit will provide
up to 196 W of output power from a nominal 48 Vdc input. The unit is designed to be highly efficient and low cost.
Features include remote on/off, output current limit protection, input under-voltage lockout and output over-
voltage latch off. This converter is provided in an industry standard quarter 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(+) pin. Only one of the resistors should be used for any given application.
