Description
The 0RLC-10T Series are isolated dc/dc converters that operate from a nominal 48 Vdc source. These units will
provide up to 12 W of output power from a nominal 48 Vdc input. These units are designed to be highly efficient
and very low cost. Features include remote on/off, over current protection and short circuit protection. These
converters are provided in an industry standard package.
