Description
The 0RCY-50T08x is isolated dc/dc converter that operates from a wide input range (36 Vdc - 75 Vdc). This unit
will provide up to 50 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 GND pin. The Trim Up resistor should be connected between the Trim pin and the Vout pin. Only
one of the resistors should be used for any given application.
