Enphase SSTART-12-20A Soft starters used for 120V pumps and HVAC

Soft starters used for 120V pumps and HVAC with load current 12A to 20A.
 
The SureStart Series soft-starter was the first of its kind invented by Hyper  Engineering over a decade ago in Wollongong, Australia. It was originally invented for use in the residential heating, ventilation, and airconditioning (HVAC) industry in Australia and Europe. In recent years, Hyper has expanded SureStart technology into commercial HVAC by offering 3 phase versions in commercial voltages. Whether it is for residential or commercial applications, SureStart’s continued success worldwide is a testament to its reliability and performance that can be rivaled by none other.
