PLEASE NOTE: Effective 2019, we no longer supply Control Techniques variable frequency drives and components. We have drives from several other manufacturers which can meet or exceed the performance characteristics of the Control Techniques line. Simply complete the form below, or contact us with the model of your current or obsolete Control Techniques drive and we’ll be glad to identify a suitable replacement.

Also, the Fincor and Saftronics lines of AC variable frequency drives, DC variable speed drives, and reduced voltage starters were once owned by Emerson but have been obsolete for several years. However, we have many years’ experience working with these drives and can quickly identify replacements capable of exceeding the quality and performance of these older drive technologies. For a suitable replacement, fill out the form below or contact us with your drive or application requirements, and we’ll handle it from there!
