The SD Series VFD is our simple, single-phase to three-phase converting solution for residential and light commercial constant pressure installations requiring 2-5 horsepower. The SD product line offers simple setup, rugged hardware, NEMA Type 3R enclosures, and a low noise oil-filled 0 - 150 psi pressure transducer. Enjoy commercial VFD quality and robustness in a drive that is easy to configure for home wells, irrigation systems, motor control, and soft start applications. They can also be configured for lead lag applications.
System setup with Perfect Pressure requires only a few minutes and is capable of controlling complex pump systems by answering 6 questions. See our Quick Start Guide for details.
The SD Series VFD's control pressure consistently, regardless of demand. The pump system runs smoothly with fewer instances of short cycling and requires a much smaller pressure tank than a pressure switch.
