Q:Laptop power adapter is used to do what
The laptop's power adapter is a device that converts 220V AC power from a power supply unit to a low-voltage direct current device for powering a laptop. Power adapter output low-voltage direct current into the computer, but also through the computer motherboard power circuit to further deal with, resulting in 1.8V, 3.3V, 5V and other sets of voltage for memory, CPU and other components to run; another power adapter to provide the power can also be related Charge control circuit to charge the battery for the laptop.
Q:Three-phase motor, quadrupole asynchronous motor to 15rpm, the inverter output how many volt voltage? The 4 V
4 volts too little, at least tens of volts
Q:Laptop warranty period is not over, the power adapter is broken, repair money?
The general adapter is only one year warranty. And even some power warranty for three months. Go to the official website of the notebook, see the specific information of the computer, which includes the computer parts of the specific warranty date and expiration date. If the warranty period, as long as the purchase of the invoice, you can go to aftermarket replacement or maintenance. Remember to bring an invoice, warranty card. It can not find the warranty card must find the invoice. General power adapter is new.
Q:What is the difference between the collector and the emitter mode?
While the base area should be very narrow So bjt is not a symmetrical device
Q:What is the base blockade in the drive?
Base blockade is to deal with ul or ce such a special application of security agencies means that when the parking limit action after the base blockade even if the program can not malfunction, relative to the emergency stop circuit more harsh they will directly disconnect the power
Q:Is the motor having a variable frequency motor and a variable voltage motor?
It should be no change it is the input / output current is v frequency is its input / output frequency is M / Hz
Q:Please recommend a high performance laptop power adapter?
Power adapter can recommend you what model you get what model ah he is a standard can not just recommend
Q:First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
And the inverter is connected to the positive and negative bk-dk electrical Han Han device,
Q:Oil-free vertical vacuum pump why a little negative pressure inverter on the torque limit
Here is not the inverter can solve the problem, you should first 220V single-phase AC rectifier for the DC (full-wave rectifier plus filter about 310 volts),
Q:On the laptop power adapter problem
Notebook power on the two specifications, one is 65W, one is 40W, 65W power supply is a discrete graphics notebook, 40W is integrated graphics notebook. Just connected to the use of power, then there is no problem. Just if you laptop battery with the light of the words, plug in the power can not be the same as with the 65W, immediately you can use the boot. Because the current is low, the charging speed is relatively slow. The other will not have any effect
