FAQ

The emitter E of the inverter inverter module and the AC output U are not directly connected together

Pairs of modules are connected in a phase branch The phase output is derived from the neutral point between the modules

The notebook power adapter flashes

The problem is very simple Well, used to know all the notebook Kazakhstan, the adapter has a light above, if it is lit that is the problem of the notebook, the other side of the notebook above also have a power indicator, the notebook above prompted the red, but not Rushed, that is, the problem of the notebook, the computer problem, you directly on the factory is finished, if the insurance, and casually find a place to repair a Kazakhstan, 50-80 yuan if the adapter is bad, buy a generic You can, but also more than 50 points, the last time I bought a bad 58 yuan, ASUS GM, to help people in the end, to give you a shop to buy the adapter, you ask the owner of Kazakhstan to get,

There is no inverter comes with simple PLC programming function

Inverters are generally digital input, and analog input, a digital output, etc., can also be controlled by means of communication. Digital input can be used as a positive and negative and reset the alarm, the analog input can be given as a speed, and how to use the inverter to see the specific model. Take the Siemens inverter, MicroMaster420,567 terminal 3 digital input, 8 for the 24V, 9 for the 0V, you can usually open the point on the 8th 24V back to 567, as a digital input, you can also directly into the switching power supply Of the 24V, but the switch power supply 0V and 9 terminals connected to the potential, or the inverter may not be able to identify the outside world 24V. (DP communication, USS communication, etc.), with the terminal input on the P0700 = 1, the user can set the command source, the panel can be input, 2, P0701 to P0703 corresponding to the three digital functions: parameters set to 1 forward, 2 for the reverse ... ... a lot of features and control methods, see the corresponding product manual like

Which machines are used for the frequency converter

Frequency converter is widely used in the speed regulation of AC motor.Varameter speed control technology is an important development direction of modern power transmission technology, with the development of power electronics technology, AC frequency conversion technology from theory to practice gradually mature. Inverter not only smooth speed, large range, high efficiency, start current is small, smooth operation, and energy saving effect is obvious. Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply, air conditioning and other fields.

What is the laptop power adapter? Is it the battery?

so that the book can be normal operation, or else you think the notebook is 220V Is the voltage at work?

Motor 2 pole and 4 pole in the inverter with what set to show

There are parameters for the number of motor poles / pole pairs or the rated speed of the motor in the inverter parameters

Who knows how the frequency converter works

2. flat wave circuit In addition, the ripple current generated by the inverter also changes the DC voltage. In order to suppress the voltage fluctuation, the inductor and the capacitor absorb the pulsating voltage (current). In general, the DC voltage of the rectifier is rectified and the DC voltage is rectified. General inverter power supply of the DC part of the main circuit in terms of margin, so eliminating the need for a simple capacitor filter smoothing circuit.

What is the IGBT? Our inverter IGBT fried,

Name is the FET, the price of this thing is more expensive,
