Specifications

Variable Frequency Inverter
1.3KV ~11KV AC Driver Inverter
2.Suitable for motor speed regulation
3.Energy saving solutions

Specification and advantages :

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.)

Q: In the case of the inverter, why can not the normal operation after removing the gearbox? The motor is 4 pole.: If there is no load, the demolition of the gearbox is the same can be run.

Q: Can different brands of laptop power adapters be generic?: Power adapter can not use, the key to see two factors. First, the interface must first be the same interface or can not use. Second, the output current, the output current must be strictly consistent, otherwise it would be very dangerous, the laptop overload of the current is very fragile. The final output voltage I personally think can have a difference of type 5V. Because the battery on the voltage requirements up and down can have 5V floating. I have also used a high 5V adapter, has been no problem, but this is just my personal view. Strictly the same as the best. Oh, for reference only! Since you can plug in the normal use, indicating that the interface is consistent, and the output voltage and current are the same. Then I can responsibly tell you, rest assured to use it, there will be no problem.

Q: How does the spindle drive system of the inverter realize the positive and negative control of the main pole?: The general inverter has an external terminal control and communication control two modes optional, select one of them can be completed ah

Q: I have a 11KW-4 pole inverter, now with the 4KW-4 pole motor, what impact?: that is, the load is very heavy; caused by over-current burning inverter

Q: Asus notebook power adapter how to open: Hi respectful ASUS users The power adapter can not be disassembled, and if your machine's power adapter is faulty, you can go to the local service center for testing.

Q: What is the laptop adapter: 2, the basic composition: input line + charger main body + output line + connector such as Acharger single-band notebook charger composition, which constitute the basic elements of the notebook charger, as inside the internal parts is very complicated.

Q: Huichuan frequency converter drag a 4-kilowatt four-pole motor to change the six pole can?: can. Re-enter the new motor parameters in the drive.Inverter motor power to 4KW, speed 980 can!

Q: Can the four motors be tuned to 2900 rpm?: Can be used, there are problems you can consult Zhoukou City bearing mechanical and electrical companies, contact the online search Zhoukou City bearing mechanical and electrical companies can search to!

Q: Three-phase two-pole motor can be used to reduce the frequency of the inverter: If you need to be very slow, you can match a four-level motor ah, even more slowly with a reducer

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.
