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 under-

voltage lockout. This converter is provided in an industry standard eighth brick package.
