Description  
The 0RCY-C2T12x is isolated dc/dc converter that operates from a nominal 48 Vdc source. This unit will provide  
up to 144 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 converter is provided in  
an industry standard eighth brick package.

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