Description
The 0RLC-25T series are isolated dc/dc converters that operate from a nominal 48 Vdc source. These units will
provide up to 30 W of output power. These units are designed to be high efficient and very low cost. Features
include remote on/off, over current protection, and under voltage lockout. These converters are provided in an
industry standard package.
