This VFD can be used for constant torque loads (such as hard starting: Air compressors, HVAC units) and variable torque loads (such as pumps, fans, etc). It can be used as motor speed control and a phase converter. Many customers bought this VFD from us to use for: Lathes, Mills, Car Hoists, Pumps and Conveyors, etc and then performance excellently.
