Description  
The 0RCY-60U12x is part of the isolated dc/dc converters that operate from a wide input range (18 Vdc - 75 Vdc)  
and can cover both 24 Vin and 48 Vin input range. These units will provide up to 84 W of output power. They are  
designed to be highly efficient and low cost. Features include remote on/off, over current protection, over voltage  
shut down, over temperature protection and under-voltage lockout. These converters are provided in an industry  
standard 1/8 brick package.

CAUTION: This converter is not internally fused. An input line fuse must be used in application.  
Recommend a fast-acting fuse with maximum rating of 8A on system board. Refer to the fuse  
manufacture’s datasheet for further information.  
Notes: 1. This converter has internal C-L-C (2.2uH-2*0.47uF+2.2uF) filter.  
2. All specifications are typical at 25 C unless otherwise stated.

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.
