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.

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.
