Description
The 0RCY-80Rxxx series are isolated dc/dc converters that operate from a nominal 24 Vdc source. These units
will provide up to 120 W of output power and 30 A of output current from a nominal 24 Vdc input. The unit is
designed to be highly efficient and low cost. Features include remote on/off, over current protection and undervoltage lockout. This converter is provided in an industry standard eighth 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.
