4KW Variable Frequency Drive
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 a motor speed control and a phase converter. The input for this VFD is three-phase, output is three-phase. You can control the different speed as you like when you use this VFD. This item use Sine wave PWN(SPWM ) for the control system and performance excellently.
