Description
The 0RCY-85T Series are isolated dc/dc converters that operate from a nominal 48 Vdc source. These units
provide up to 100 W of output power. These units are designed to be highly efficient and cost-effective.
Features include remote on/off, short circuit protection, over current protection, over temperature protection, input
under voltage lockout, and output over voltage protection. These converters are provided in a compact, 1/8 brick
industry standard package.
