Q:What is the laptop adapter
3, classification: according to the use of points (AC, such as home, office use AC are called AC; DC, such as the car, the aircraft are used DC are called DC); by the output voltage current (12V series, ASUS more commonly used, such as ASUS 12V3A; 15V series, TOSHIBA more commonly used, such as TOSHIBA 15V3A, 15V4A, 15V5A; 16V series, SONY, IBM more commonly used, such as SONY 16V4A, IBM 16V4.5A; Series, HP, such as HP 18.5V3.5A; 19V series, such as ACER 19V3.42A, TOSHIBA 19V3.42A; 19.5V series, such as DELL 19.5V3.34A, SONY 19.5V4.1A; 20V series, such as DELL 203.5A , LENOVO 20V3.25A; 24V series, such as APPLE 24V1.875A; 9.5V-24V series, such as Acharger ALS-185A35C).
Q:Can the laptop power adapter be generic?
Not necessarily, the laptop power adapter has two interfaces for input and output. 1. Input interface is connected to the power outlet, generally divided into two holes and three holes, as well as round mouth and flat mouth of the points; 2. Output interface is connected to the computer side, size, length, diameter, diameter, the pin may have differences, common are: diameter 2.5MM, ordinary mouth, mainstream interface; OD 1.7MM, small mouth; MM, big mouth with a needle, round mouth with a needle and so on. 3. Different voltage, different brands of laptop power adapter voltage is not the same 4. Current is different, different brands of notebook computer power adapter current is not the same In summary, the laptop power adapter between the different types, basically not common
Q:What is the difference between the electronic governor and the frequency converter on the motor speed regulation?
Electronic governor is the use of control thyristor conduction angle to change the motor supply voltage, the motor characteristics of the curve down to change the speed of asynchronous motor. Its characteristics are as follows: the motor speed adjustment range is small, low speed when the motor load capacity is poor, the speed decreases, the motor torque decreases, not applicable with constant load, when the speed is low, prone to stall phenomenon; Applicable to fan load. Inverter speed is to change the frequency of the motor to achieve the AC asynchronous motor speed adjustment, speed adjustment balance, the motor load characteristics do not change with the speed change, suitable for load adjustment and constant torque adjustment. Excellent performance, but the cost is higher.
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:Motor a speed, the inverter will burn what is going on, the inverter is a large yuan
Inverters Have not heard of it! East yuan heard. The inverter is most likely to be damaged by the motor is running suddenly grounded, the possibility of frying the module more than eighty percent, since a little better brand will blow up! Overload, overcurrent, short circuit, lack of phase caused by damage to the inverter, then the quality of the inverter is so good, and indeed the basic functions of these inverter protection.
Q:What are the types of power adapter used in notebooks?
With the increasing popularity of notebook computers, the power requirements have increased. In addition, because the battery capacity (or density) increased, charging requirements also increased - so the laptop computer power requirements have doubled. However, larger and / or hoter power adapters are not an attractive option for millions of users who carry laptops around the world. Attractive is to have a compact, but instantly charged laptop adapter. Of course, it will not produce heat, and will not cost too much. In recent years, the development of electronic products has not increased the hope in this regard, and whether the future revolution can be achieved is still a pending issue. We also want to use a laptop adapter that can be used globally without the need for a 110/220 volt operating voltage selector switch - so the laptop adapter must be designed for truly universal line voltage operation. At the same time, regulators and OEM expectations also play a role.
Q:Notebook power adapter on how to look at power
It should be noted that there are many in Japan to buy a notebook or over there in the parallel imports, input only support 110V in China is not used, because the Chinese standard is 220V. Now the subject is 90W 20V. Output voltage and power will be identified, such as the target for the 90W 20V, that output power is 90W, the output voltage is 20V. If only the output voltage and output current are identified,
Q:What is the frequency converter used to do, why some motor with the inverter?
Frequency converter is widely used in the speed regulation of AC motor.Varameter speed control technology is an important development direction of modern power transmission technology, 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.
Q:What is the difference between AC and DC frequency converters?
Advantages and disadvantages: Advantages: inverter air conditioner with variable frequency power supply, inverter compressor, electronic expansion valve and microcomputer technology, the organic combination of air conditioning to further improve the performance, the use of room temperature fluctuations, better comfort, the better Power supply voltage fluctuation is not sensitive, the compressor starts, the general non-stop, cooling capacity in the range of 35% to 117% change, to avoid the frequent open air-conditioning, to extend the life of the compressor, while efficient, Features. Disadvantages: the price is more expensive, compared with ordinary air conditioning, about 1/3 to 1/4 of the price, at the same time, because the inverter air conditioner control system and frequency conversion system is more complex, higher requirements for components, compared to ordinary air conditioning , Inverter air conditioner failure rate is high, and, due to the use of frequency conversion technology, at the same time, will produce harmonic pollution. What is DC inverter air conditioner? DC inverter air conditioner is relative to the AC inverter air conditioner, in fact, its name is not correct, because the DC and no frequency, it is by changing the DC voltage to adjust the compressor speed, thus changing the air conditioning cooling capacity, It can only be said to be a DC variable speed air conditioning, not strictly in the sense of inverter air conditioner.
Q:Laptop power adapter how to detect?
No load voltage, DELL plug more special, the middle needle no load measurement is no voltage, the outer ring outer house and the wall only 19.5V voltage
