Description

The 0RCY-50T12x is isolated dc/dc converter that operates from a wide input range (36 Vdc - 75 Vdc). This unit

will provide up to 72 W of output power. The unit is designed to be highly efficient and low cost. Features include

remote on/off, over current protection, over voltage shut down, over temperature protection and under-voltage

lockout. This converter is provided in an industry standard 1/8 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.
