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: Laptop adapter
- This principle is not, try, look at how the charge situation, if you can charge, can be filled, just a long time, to no harm However, the heat may be high, long-term so, there is a risk
- Q: Laptop power adapter in the ring is how is it?
- Notebook power adapter generally use the switch circuit, the output 12V DC power supply, as the notebook DC / DC converter circuit power supply; In the switch circuit, the most prone to "creak" sound is the switch transformer coil (ringing), or high-voltage filter capacitor (fire);
- Q: Lenovo laptop power adapter side of the feet which is positive
- Lenovo laptop power adapter side of the mouth there are clear signs positive and negative, N on behalf of the positive, L on behalf of the negative, it is recommended to carefully look at that you can know.
- Q: Abb inverter s510 with water circulation pump why the motor fever. The motor is 2 pole
- Check the inverter operating power factor, straight up the motor to see if it is overheating
- Q: Will the asynchronous motor pole change the number of speed control can also be combined with the frequency converter
- but the use of the inverter is based on changes in the load by changing the frequency of power into the motor at any time speed control, you can achieve a smooth and accurate stepless speed control is Now widely used in a speed control method, especially for the load often change or often in the light load operation of the motor.
- Q: How to view your own laptop power adapter is how much tile?
- 1, the power adapter has a logo, you can find their own look, close to the paper or direct letterpress printed with the voltage, current and power. If there is no write power, the direct voltage multiplied by the current is the maximum power. 2, if the power adapter only identifies the output voltage is 20V, the output current is 4.5A, then we formula W (power) = V (voltage) xI (current) to calculate. Calculate the formula with a power to know the output power is 20 × 4.5 = 90W.
- Q: Inverter with 2.2KW 6 pole motor. 1 minute 8 times reversing often burn the motor, how to solve. For the 2 pole 4KW motor is the same.
- 7 seconds more than a change, too often. It is estimated that the inverter will not work. Suggest:
- Q: What is the base blockade in the drive?
- After the base is blocked, the power tube is fully closed to protect the power tube.
- Q: Inverter 0.2KW, the motor speed requirements down to 4 turn, the motor pole 4 pole. Can the drive drive the motor?
- Can, but this is a test product, the application does not try!
- Q: What is the meaning of the bipolar polarity in the inverter ah There is a +10V signal input is a -10V What is the meaning of ah?
- Bipolar input is positive and negative. Bipolar input is generally used to directly through the external reference or potentiometer to achieve the motor forward and reverse switching, without having to switch all the way to switch the signal (switch).
