Description  
The 0RHB-D0T12W is isolated dc/dc converter that operates from a nominal 48 Vdc source. This unit provide up  
to 240 W of output power from a nominal 48 Vdc input. This unit is designed to be highly efficient and low cost.  
Features include remote on/off, over current protection and under voltage lockout. This unit is provided in an  
industry standard half-brick package.

Output Trim Equations  
Equations for calculating the trim resistor (in k) are shown below. 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.
