Product Description

660V 1100V 3300V 6600V Medium Voltage Inverter VFD VSD


ZUN/ZK SD3000 series Medium Voltage VFD



This medium voltage 3 level VFD are widely used in which the fields of electric power, iron and steel, petroleum, mining, chemical, cement, automobiles, and utilities


It has several advantages as following:

1) Simple structure and small size;

2) Compared with the two levels, the device can achieve 2 times the voltage output with the same voltage level;

3) Reduce the common mode voltage of the motor;

4) Reduce common mode interference to the power grid;

5) It is convenient to realize the two-way flow of energy and the four-quadrant operation of the motor;

6) The output du/dt is reduced by half compared to the two levels;

7) Compared with the two levels, the number of phase voltage output levels increases and the output harmonics decrease.


1). Substantial reduction of harmonic current on power source side

2). Total inverter effi ciency as high as approximate 97%

3). Source power factor as high as 95% or more

4). High-reliability

5). Vector control

6). Easy maintenance



1). Construction Materials: Kiln head cooling fans, Kiln tail heating fans, Grinders, Cement rotary kilns

2). Petrochemical Mining: Catalytic cracking unit, Hydrogenation compressor, Oil and gas transmission device, Blowers/pumps/pelletizer

3). Mining: Belt conveyers, Grinders, Mine air circulation blowers

4). Iron and steel: Blast fumace blowers, Primary/secondary dust blowers, Dry quenched coke circulation blower, High-pressure phosphorus ejector pump, Blowers/water pumps, Crusher

5). Electric power: Induced draft fan/forced draught fan, Primary/secondary blowers, Condensation pumps, Recirculation pumps, Feed pumps

6). Others: Water conservancy, utilities (pumps), Sugaring (mill), Test crew Internal mixer
