4.16kV /6kV Series VFD
3kV /3.3kV Series VFD
6.6kV Series VFD
10kV / 11kV/ 13.8kV Series VFD


Features :


Medium Voltage Variable Frequency Drives are designed to be highly reliable with high-performance, yet easy to use.It can satisfy users' need for changing the speed of fans or pumps,as well as improve the productivity. The series are compatible with all types of three-phase medium voltage asynchronous motors. The VFDs which are compatible with medium voltage synchronous motors are in the final stage of development.  series of medium voltage VFD manufactured with the new type of IGBT with microprocessor control have the qualities as follows:
1. Voltage resource VFD, direct input of 3,3.3,4.16,6,606 and 10 kV,direct output of3,4.16, 6,6.6 and10 kV,no output transformer necessary. High input power factor, low harmonic current, no power factor corrective capacities and harmonic filters required.
2. Sinusoidal multi-level PWM output waveform, no output filter required, can be directly connected to standard induction motor,no harm to the insulation of the cable or the motor, low harmonics of the motor, reduction of vibration of the shafts or the vanes,with the maximal length of the output cable of 1000m.
3. Friendly human-machine interface.
4. Modular design of the power circuits simplifies maintenance routine.
5.The medium voltage circuits are linked with the controller by the optical fibers,which keep the controller safe and away from the disturbance.
6. The complete fault monitor circuit, accurate fault alarm and protection.
7. Integrated cooling blower
8. The control logic can be conveniently changed with the help of the integrated PLC.
9. Offer both field control and remote control in monitor station, providing convenient controlling options.
10. Support most of the industrial standard protocols (Profibus, Modbus, TCP/IP, etc.)
11. Compatible with industrial standard signal of 0-10V/4-20mA
12. Able to operate at either open loop control or closed loop control status with the integrated PID regulator.
13. Complete system parameter setup function of VFD
14. Easy installation
15. Excellent performance/price ration

Q:Can the laptop power adapter be generic?
Not common. Different computer adapter interface is not the same, and the voltage, current is not the same. If just the same, you can use, the voltage can also be used.
Q:What is the single axis of the inverter and multi-axis applications
Inverter is the application of frequency conversion technology and microelectronics technology, by changing the motor power supply frequency and amplitude of the way to control the AC motor power transmission components.
Q:Three motors, if coupled with the governor speed, is it necessary to add the inverter?
 Fifth, the hydraulic coupler speed: hydraulic coupler is a hydraulic transmission device, generally composed of the pump wheel and turbine, when the pump wheel in the prime mover driven under the rotation, in which the liquid is driven by the blade and rotation, in the Under the action of centrifugal force along the outer ring of the pump wheel into the turbine, in the same turn to the turbine blades to thrust, to drive the production machinery operation. Through different hydraulic (lubricants and turbines) to achieve speed.
Q:Why G120 inverter to be equipped with 4-pole motor?
I add point with the premise of the inverter is to understand the mechanical load characteristics (or process, etc.), can the parameters set.
Q:18: 5 kilowatts bipolar multi-pole pump motor with inverter
Under normal circumstances, with 15KW inverter on it.
Q:Laptop power adapter bad what is the phenomenon?
If you unplug the power adapter is good, then your adapter has a problem, you are the original adapter, I encountered the imitation of the adapter has this problem,
Q:Jd1a-40 motor speed controller and how to connect the motor
First, variable pole alignment speed method This method of speed control is to change the stator winding winding red method to change the cage motor stator pole pairs to reach the speed control target, the characteristics are as follows: This method is suitable for production machinery which does not need stepless speed regulation, such as metal cutting machine, lift, lifting equipment, fan, water pump and so on. Second, the frequency control method Frequency control is to change the frequency of the motor stator power supply, thus changing the speed of its synchronous speed control method. Frequency converter system can be divided into exchange - DC - exchange converter and exchange - exchange inverter two categories, most of the current domestic use of cross - straight - cross frequency converter. Its characteristics: This method is suitable for the requirements of high precision, better speed performance.
Q:Inverter ACS355 If the speed is outside the allowable range, how to set the limit value
Remember, 2001 this should be set to a negative number, set to a positive number of your speed will never be less than this value.
Q:What is the IGBT? Our inverter IGBT fried,
Name is the FET, the price of this thing is more expensive,
Q:Fuji inverter motor set the number of poles will not have any effect?
The number of motor poles corresponds to the speed of the motor, the number of poles is not set when the speed of the control error, in the high speed requirements of the transmission is not allowed.
