Description
The 07CY-85T Series are isolated DC/DC converters that operate from a nominal 48V source. These units
provide up to 100W 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.
