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 inpute for this VFD is 1 or 3 phase as you like. You can control the different speed as you like when yo use this VFD. Many customer bought this VFD from us to use for: Lathes, Mills, Car Hoists, Pumps & Conveyors, etc and then performance excellently. This item use Sine wave PWN(SPWM ) for the control system and performace excellently.
Following, please see the item picture firstly, then bases on the picture, I will guid you how to install this VFD
R.S.T------Input terminal of AC line power.(220V class, for both single/three phase, single phase connected to any two phases)
U.V.W-----Output terminal of the inverter
P+.PR----Connector for braking resistor.
E----------Ground terminal: the third method of grounding for 220V and special grounding for 380 V of Electrical Engineering Regulations.
