SD Series Variable Frequency Drives
Designed specifically for pumping applications
Phase Technologies has designed a simple, phase converting solution for residential and light commercial constant pressure installations (2-10HP). The SD product line offers simple setup, rugged hardware, NEMA Type 3R cabinets, and a top of the line oil filled pressure transducer.
Return trips are expensive and can many times lead to a poor customer image of the installation. Phase Technologies has produced a product line specifically to solve this problem, the SD series. With pricing that even the most budget-minded customer will appreciate and a 3-year warranty, the SD series is the best choice for small constant pressure applications.
Standard with all SD and 2XD systems, demand-driven constant pressure control for home wells is now inexpensive, reliable, and a luxury available to all homeowners thanks to Perfect Pressure™. Perfect Pressure™ only requires a few minutes of setup time and is capable of controlling the most complicated pump systems with ease. With constant pressure, pump systems run smoothly with fewer instances of short cycling. The SD Series VFD controls pressure consistently regardless of demand.
