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: Is the inverter output current proportional to the output torque?: When 50HZ or more, the voltage is not increased, the magnetic flux decreases. P = T * n / 9550, if the motor output torque does not change, the current will increase, the motor heat overload

Q: Laptop power adapter aging: First, the laptop power adapter is digital transformer, under normal circumstances either damaged, either available, no low voltage. Second, the notebook to play large games up to make the notebook because of poor heat dissipation caused by high temperature automatically shut down, not because of lack of power caused by automatic shutdown.

Q: My inverter is the era TVF8000 series, the motor is 15KW6 pole motor, has been used for 3 years.: If the frequency converter is selected according to the motor rated current, then the motor current exceeds the rated current, the inverter will become overcurrent protection In this case, that is, when the inverter began to select the amount of time to stay the lack of the same power, inverter general type than the fan pump type current capacity of a high grade If the inverter selection is no problem, then please see whether the inverter is working temperature is too high, too high will cause the electronic components to resist the decline in current. First, check the inverter to work the ambient temperature, the second Please check the inverter fan is damaged, clean down the inverter fan channel and fan to see if there is no plug

Q: Can the notebook's power adapter be mixed?: This is a 90W power adapter This is Acer's 65W power adapter Here need to explain: General in the power adapter only shows the output voltage and current, not marked wattage, need to calculate their own. The value obtained by multiplying the number of voltages and the number of currents is the wattage. More on notebooks Related topics: Notebook forums hope that the above information is helpful to you

Q: Who knows how the frequency converter works: The inverter is actually an inverter, which first turns the alternating current into direct current, and then switches the DC power with the electronic components into AC power, and the inverter is equipped with a variable 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: Short-term short-circuit converter DC link positive and negative will damage the inverter?: This short circuit may not necessarily line, the inverter fan has three, one is no speed line, two are pulse, three are switching signal (this is very little, I only encountered several),

Q: The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!: The following describes the selection of the inverter Note: The inverter selection is mainly driven by the load characteristics and the actual motor current to set, in addition, there are the following precautions. 1, the environment: for some high temperature (higher than 50 degrees), high altitude (more than 1000 meters) of the application, the inverter selection should be appropriate to leave a margin to ensure that the inverter and motor life. 2, distance: the location of the inverter installation and drive the distance between the motor more than 50 meters, the frequency changer selection should cooperate with the reactor to reduce the carrier frequency. 3, a drag: a drive drag more than one motor, if the middle of the cable is too long, universal inverter selection will enlarge the use of a file, and each machine should be installed behind the fuse.

Q: 55 瓩 4 pole motor with a frequency of one hour can save much electricity: Such as: 55KW motor full load operation, 1 hour with 55 degrees of power (according to the motor power slightly different changes),
