Smart-Boost™ is a new breed of Digital Rotary Phase Converter. Our Smart-Boost™ Rotary Phase Converter technology aids in the startup of motors external of the phase converter downstream. The Smart-Boost™ Controller uses solid state switching to re-engaging the start capacitors at zero degree crossing. Which in turn, surges 600% more current to the motors during their startup.
