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 1 phase . 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 performance excellently.

About the item:

【Connection way】Input:220VAC(+/-5%) 1 or 3phase(for single-phase input, just connect the input wire to the R and S terminals) Output:3phase 220v. Frequency:0-50hz/60hz. 0-400hz
【Multiplex terminal】Unlike other inexpensive VFDS, this VFD has two sets of terminal functions,Rich of digital and analogy control terminals for versitile control,optional MODBUS (RS485) extension,diversified parameter setting
【Safety performance】Take advantage of various protection ways such as Motor short-circuit detection at power-on, output phase loss protection, over-current protection, over-voltage protection, under-voltage protection, overheat protection, overload protection and etc.
【Good Noise Control】The product has the advantages of low noise and low electromagnetic interference, which are achieved by the excellent PMW control technology and component compatibility design. There is enough space for cooling between each component, and the product casing is designed with multiple holes, the above features can make this VFD have a longer service life.
【Warranty】: Lifetime warranty .If there is an error code in the product and you do not know how to operate, please contact the seller.
