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:Servo control system can give the inverter signal,: If two motors are to be synchronized, only two servomotors are used, one is set to spindle and the other is set to slave.

Q:Laptop power adapter leakage: In fact, the adapter does not matter fake real goods, brand machine adapter are also purchased. According to my point of view, or I choose the words: casually buy one can, dozens of dollars on the line. In fact, the adapter is also worth tens of dollars, selling a few hundred dollars are also almost the same thing. Adapter is a small switching power supply, 100W or so, the value of that price.

Q:Three motors, if coupled with the governor speed, is it necessary to add the inverter?: ??Third, the cascade speed: Cascade speed refers to the winding motor rotor loop in the adjustable resistance to change the motor slip, to speed the purpose of the past, the most widely used.

Q:Will the laptop's power adapter is not the original good?: As long as the power and current are equal or slightly larger than the original adapter, but the voltage must be equal to the original adapter on the line.

Q:Three-phase motor, quadrupole asynchronous motor to 15rpm, the inverter output how many volt voltage? The 4 V: The voltage is basically the same, the inverter changes the frequency of the power supply, not the voltage.

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:How to disassemble the notebook power adapter: HP laptop power adapter for the whole design of small sealed, you can follow the following steps to dismantle: 1, laptop power adapter for the injection molding package or with a strong adhesive glue, without any screws, so generally only with violence Cracked. However, as long as the method properly, after the dismantling of the power adapter can be restored to the original, do not carefully observe almost no traces of open.

Q:Laptop power adapter problem: Third, since the book is very old, the original factory may not have such a transformer spare parts, then a reasonable idea is to let this book off, rather than the provincial money to take their own little life joke, a notebook and then expensive It will not be more expensive than your life, the money is very unreasonable province. A notebook with a decade is also completely considered the best use of the matter, you are stingy stingy Ye Hao, there are emotional sustenance worth mentioning, it should be eliminated or out of it.

Q:Lenovo g450 laptop power adapter specifications is what?: Lenovo g450 laptop power adapter specifications is what? Wrqwgp520 | viewed 4426 times Recommended at 2016-05-26 08:52:41 Best answer Lenovo Lenovo 19V4.74A G450 G470 Laptop AC Adapter: 【Power supply technical parameters】 1. Input voltage: AC100-240V.50-60Hz.1.5A 2. Output voltage: 19V 3. Output current: 4.74A 4. Work efficiency:> 85% 5. Output power: 90W 6: Input interface: Plum triangular interface 7: Output interface: 5.5 * 2.5

Q:The parameters of the inverter is 4, 6 motor can be used: The inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on. The inverter will adjust the voltage and frequency of the output power by the breaking of the internal IGBT, according to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition, the inverter has a lot of protection , Such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, the inverter has also been a very wide range of applications.
