Q:Is the laptop power adapter AC and DC?
Most laptop power adapters can be used for 100 ~ 240V AC (50 / 60Hz). Basically, most of the notebook computers are external power supply, with a power cord and the host connection, which can reduce the size and weight of the host, only a very small number of models built in the host power.
Q:Do you need to rectify before switching?
Need to rectify. The inverter is actually an inverter, which first turns the alternating current into direct current, then switches the DC power with the electronic components, changes to alternating current, and the general-purpose inverter is equipped with a thyristor and an adjustable frequency The frequency is adjustable in a certain range, and it is used to control the number of revolutions of the motor, so that the number of revolutions can be adjusted within a certain range.The frequency converter is widely used in the speed regulation of AC motor. Technology development direction, 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 and other fields. Generally divided into rectifier circuit, flat wave circuit, control circuit, inverter circuit, and so on several major parts.
Q:What is the output voltage of the laptop power adapter?
16V to 20V, different brands may be different, 19V, 20V more.
Q:The laptop's power adapter is too hot to do
Installed adapter heat should be no problem, I am now under the books, the fan mouth is very hot, the weather may be more and more hot it
Q:What is the frequency converter used to do, why some motor with the inverter?
Speed control, there are speed requirements of the place are in the inverter
Q: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.
Q:Inverter alarm a043, how is it
When a signal failure occurs, use the DTI board, if necessary, change P215. With P806 (Follow the parameter description) during operation can be converted to no encoder operation A043 is: n-actjump exceeds the allowable change speed of the speed encoder signal (P215) In addition, for the synchronous motor (P095 = 12): The motor speed is 2% higher than the inverter release time point. The inverter in the ready state can not exit. Check processing: Check if the cable is disconnected Check the tachometer to shield the ground Not only on the motor side but also on the inverter side The encoder cable does not allow disconnection Use only recommended encoders The encoder cable is not allowed to be laid with the power cable
Q:Does the inverter set the number of poles to match the number of poles of the motor?
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.
Q:The laptop power adapter is hot
Notebook power adapter in the power after the use of hot is a normal phenomenon, do not worry, no danger, it will not explode. The length of this time does not matter, in the use of one or two hours will become very hot, but will always keep this temperature. And the notebook's power adapter shell are high temperature, will not burn. Notebook power adapter in addition to hot, you may hear the sound, the sound is not, very small. This sound is not a big problem, it is the power adapter power after the power filter sound, so plug in the plug after. Any power adapter basically has a sound. You can listen carefully, the surrounding environment is particularly quiet when you can hear. Power adapter is a transformer, inside the transformer coil in the AC will produce Zizi sound. Some power adapter use a long time will have this sound, but no big problem, you can continue to use. As long as the sound is not high outrageous do not control. Laptop power adapter hot and sound basic are considered normal, unless the temperature is too high or even damage to the shell or the sound is very obvious, this is a problem. The general does not affect the use of the adapter bad to buy a can. Notebooks have to protect the isolation circuit, do not worry about damage to the notebook.
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.
3. Can try (the effect is not necessarily), for a large inverter and variable frequency motor, and the inverter installed braking unit, braking resistor.
