Description
The xRSB-40U series are isolated dc/dc converters that operate from a nominal 24 Vdc or 48 Vdc source. These
units will provide up to 40 W of output power from an 18 Vdc - 75 Vdc wide input range. 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.
