LMI DC4500 Part Number Configuration Matrix

Please call is if you any questions about product selection or how to decipher part numbers. Not all combinations are valid or available for sale. Best practice is to keep like voltages together when building out a part number using this matrix. 

Example: DC4500111A-1 is a good part number because both Power Supply and Voltage choices match 115 VAC. However DC4500121A-1 is not valid because you would not want to mix 115 VAC Power Supply and 230 VAC Voltage with 115 VAC Receptacles.
