The Essential Series VFD is our solution for single-phase residential and light commercial constant pressure installations for both 2 and 3 wire pump motors. The ES offers simple setup, rugged hardware, a NEMA Type 3R enclosure with powder coated finish and insect guards. Enjoy industrial VFD quality and robustness in a drive that is easy to configure and affordable.

The ES was specifically designed to help ensure the VFD is properly configured the first time. Installation is easy and our step-by-step parameter setup gets things up and running fast.
