SD3000 Series 37kw-5000kw Medium Voltage Inverter VFD 660V 1100V 3300V 6600V

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

ZUN/ZK SD3000 series Medium Voltage VFD

Description

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.

Features:
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

Application
