Description  
The 0RCM-20S/30S “Cimarron” Series are isolated DC/DC  
converters that operate from a nominal 48 VDC source.  
These converters use a full bridge power train to provide isolation and step down. These units will provide up to  
240 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 quarter-brick package.

Notes: 1. Change last character in part number from “L” to “H” for Active High On/Off Logic (e.g. 0RCM-20S12H).  
2. Add “G” suffix at the end of the model number to indicate Tray Packaging.  
3. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.
