Description
The xRSB-50T series are isolated dc/dc converters that operate from a nominal 48 Vdc source. These units will
provide up to 60 W of output power from a nominal 48 Vdc input. These units are designed to be highly efficient
and low cost. Features include remote on/off, over current protection and under voltage lockout. These converters
are provided in an industry standard sixteenth brick package.
