This Variable Frequency Drive Inverter VFD can be used for constant torque loads (such as hard starting:Air compressor,HVAC units) and variable torque loads (such as pumps,fans,etc). It can be used as a motor speed control and a phase converter. The input for this VFD is 1 or 3 phase as you like. You can control different speed when you use this VFD. Most of our customers bought this VFD from us to use for: Lathes, Mill, car Hoists, Pumps & conveyors, etc. This item use sine wave PWN (SPWM) for the control system and performance excellently.
