Description
The 0RCY-60T Series are isolated dc/dc converters that operate from a nominal 48 V source. These units
provide up to 60 W of output power from a nominal 48 V input. These units are designed to be highly efficient
and low cost. 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 an
industry standard eighth brick package.
