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:The laptop power adapter is burned: To be sure, the power adapter has a problem ~ ~ I suggest you if the warranty period to go after the sale of a ~ ~ If the insurance on Taobao Amoy on a ~ ~ ~

Q:Do you need to rectify before switching?: There are two ways to convert frequency, that is, cross and cross the intersection, the latter need a direct current, need no rectification, depending on your DC situation.

Q:Why G120 inverter to be equipped with 4-pole motor?: On the upstairs that the motor parameters to be set on the possible, such as voltage, current, power, power factor, rated efficiency, rated frequency, rated speed, motor overload factor

Q:The relationship between the power supply of the notebook and the battery: 2, when the laptop turns on the power adapter, and the battery power is low, the charging circuit detects the battery power is lower than the set value, the power adapter will side of the host power supply, while the battery charge. After the charge is restored, it is restored to the power supply state directly from the adapter. Therefore, the relationship between the power supply of the notebook and the battery is that the battery is charged by the power adapter when the battery level is below the set value.

Q:Motor nameplate on the standard 2P, I set the number of motor pole in the inverter, is set 2 or 4 pole?: 1,2P refers to the number of motor poles, so it is certainly even 2, if the inverter is set to determine the number of motor poles, please write 2P value, if 2P = 4, please write 4 3, look at the nameplate on the motor rated speed for how much, you can confirm the number of motor poles. (N = 60f / p) P: pole pairs

Q:Is the motor having a variable frequency motor and a variable voltage motor?: Motor with DC and AC motor, variable frequency motor and fixed frequency motor, string motor, that is, I have not heard of a transformer motor.

Q:What is the laptop power adapter? Is it the battery?: Notebook power adapter, of course, is not referring to the laptop battery.

Q:Inverter 0.2KW, the motor speed requirements down to 4 turn, the motor pole 4 pole. Can the drive drive the motor?: Can, but this is a test product, the application does not try!

Q:Old printing machine transformation, 37KW6 polar frequency motor with brake, inverter 55KW, now found running,: It should be the inverter problem, I have encountered before, followed by the inverter upgrade was resolved. Is to replace a set of power board, power board, CPU board.
