Description
The xRSB-50R08x series are isolated dc/dc converters that operate from a nominal 24 Vdc source. These units
will provide up to 40 W of output power from a nominal 24 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.
