Variable frequency inverter (AC motor speed drive, VFD) manufacturer & supplier in China

Our vector control AC drive is our new generation products include a wide range power drives in low voltage for single phase (1.5kW, 2.2kW for 220VAC to 240VAC) and three phase (0.75kW to 630kW for 380VAC to 460VAC), with ingenious appearance & design as well as excellent performance, powerful & stability functions, suitable for a wide range of applications.


the three phase ac motor drives power range are from 0.75kW to 630kW in 380v, 400v, 415v, 420v, 440v, 460v integrated RS 485 & Modbus communication protocol for easy real time control for most kinds of applications, it can easy achieve soft start & stop to protect the ac motor from high-current impact and make the power grid more stable.

Our variable motor speed drive can continuous running even if the electric power off in a certain time which can be set manually, this new & advanced feature allows the machine work automatically in the unstable electric power area, even more, it can track the asynchronous ac motor's speed in real time and start at the assigned speed when the power on, this makes the ac motor work more smoothly with less maintenance.

Adjustable speed drive (ASD) also knows as adjustable frequency drive (AFD) is the best solution for induction ac motor in energy saving application. Our adjustable motor speed drive (ASD) can continuous running even if the electric power off in a certain time which can be set manually.

Single phase AC drive normally is used in 200V AC to 240V AC in low power applications, like small pumps. The AC motor's input need to be three phase as all of the drives are three phase output. 1 phase AC drives power range from 0.4kW to 2.2kW.
