FAQ

How to view your own laptop power adapter is how much tile?

1, the power adapter has a logo, you can find their own look, close to the paper or direct letterpress printed with the voltage, current and power. If there is no write power, the direct voltage multiplied by the current is the maximum power. 2, if the power adapter only identifies the output voltage is 20V, the output current is 4.5A, then we formula W (power) = V (voltage) xI (current) to calculate. Calculate the formula with a power to know the output power is 20 × 4.5 = 90W.

Notebook plug in the power adapter lights, but can not open the machine

Put the board under the re-installed, try and then boot. Asked: This is the case of removal, with the battery can boot answer: Then put the battery on the computer, and then use the power splitter to see if you can. If not I do not know, is the computer question to ask: This can be

Laptop power adapter bad what is the phenomenon?

Either the power is bad or the machine on the power supply module is bad to repair service

Is the laptop power adapter high temperature normal? Is there anything else?

In fact, I am also facing such a problem, but I have solved: First: you put the battery together, together with the power adapter, 1 hour after you will feel very hot, it is estimated that you say this. Although your battery is full of electricity. Second: the battery removed, and then use the power adapter, 1 hour after you will feel the general heat, much better than the first case. If you follow the above operation is what I said the same situation, it shows that your power adapter is no problem, because I specifically looking for professional after-sales such a problem, and later also detected the battery, are normal, so if you want is not very Hot, you can remove the battery.

What is the laptop adapter

4, the working principle: the use of unstable power supply switching power supply principle through the conversion circuit into the notebook computer needs constant voltage DC, to the laptop computer power supply and charging; it is worth noting that: this conversion circuit, there must be protection circuit (Overcurrent protection circuit, overvoltage protection circuit short circuit protection circuit, etc.), to prevent accidents, the protection of the laptop will not burn.

What is the single axis of the inverter and multi-axis applications

The frequency changer mainly consists of rectification (alternating current direct current), filter, re-rectification (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on.

Will the 75KW4 pole motor can be used to increase the speed of the inverter?

can! The output frequency of the inverter is higher than 50HZ, the speed of the motor is higher than the rated speed. In a certain range, the higher the frequency of the inverter, the faster the motor speed.

Does the inverter set the number of poles to match the number of poles of the motor?

The number of motor poles corresponds to the speed of the motor, the number of poles is not set when the speed of the control error, in the high speed requirements of the transmission is not allowed.
