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.

Output Trim Equations
Equations for calculating the trim resistor are shown below (Unit: kΩ). The Trim Down resistor should be
connected between the Trim pin and Ground pin. The Trim Up resistor should be connected between the Trim pin
and the Vout. Only one of the resistors should be used for any given application.
