The present operations of Synergy Development, LLC are involved in the repair, restoration, and design of custom production line manufacturing equipment. 

The operations of Emission Control, Ltd. have been closed for many years.  Since the original website is no longer in service, the domain name is now available for sale.  Some piece part inventory and manufacturing equipment for the production line are still available for sale.  Interested parties may contact us for a full description.

The "Datasheet" section is provided as a service to find adequate substitutes, since the need for replacement filters must be filled through new sources. 

The "Technical Notes" section contains information, written for the engineer, on some of the technical aspects of using powerline EMI filters in real world applications.
