Description
The 07LC-25Txx0 series converters are isolated DC/DC converters that operate from a nominal 48V source.
These converters provide up to 25W of output power. These units are designed to be high efficient and very low
cost. Features include remote on/off, output adjust, short circuit protection, over current protection, over-
temperature protection, and input under voltage lockout. These converters are provided in a compact, through-
hole package that is easy to use and provides good thermal performance, and are pin-to-pin compatible with the
Emerson AG25 Series.
