Q: Is it possible to use a different laptop's power adapter?: It is recommended to use the original comes with the adapter, different adapter output voltage is not the same

Q: Ordinary 4-pole motor Under the control of the inverter, the higher the speed, the higher the power or the slower the power: It is wrong; the higher the speed is not equal to the greater the power;

Q: How is the notebook with a power adapter?: Refer to the following factors when purchasing: Choose the brand: The principle is to choose the same type with the brand, if not, it can only find other brands. Now online to sell a lot of notebook power adapter are cut corners of the substandard products, the normal use of what should be no problem, once the accident will burn your laptop, save dozens of pieces but burn thousands of pieces of notebook worth the candle. (Such as the actual only 19V3.42A, but the standard 19V4.74A, this will lead to a very slow charge, and even damage the battery and laptop computers. There are some protection removed, this more horrible, there Accidentally burn the laptop.

Q: What are the differences and links between the soft starters and the frequency converters, and their respective principles and uses?: Soft starters and frequency converters are two completely different uses of the product. The frequency converter is used for the need for speed control where the output not only changes the voltage but also changes the frequency; the soft starter is actually a voltage regulator for the motor to start when the output only changes the voltage and does not change the frequency. The frequency converter has all the soft starter functions, but its price is much more expensive than the soft starter, the structure is much more complex. Soft starter (soft starter) is a set of motor soft start, soft stop, light load energy saving and a variety of protection functions in one of the new motor control device, known as the Soft Starter abroad. The softener uses a three-phase anti-parallel thyristor as a voltage regulator, which connects it between the power supply and the motor stator. This circuit, such as three-phase full-bridge rectifier circuit. When using the soft starter to start the motor, the output voltage of the thyristor gradually increases, the motor gradually accelerates until the thyristor is fully conductive, the motor works at the mechanical characteristics of the rated voltage, smooth start, reduce the starting current and avoid starting the overcurrent trip. When the motor reaches the rated speed, the start-up process ends, the soft starter automatically uses the bypass contactor to replace the completed thyristor, providing the rated voltage for the normal operation of the motor to reduce the heat loss of the thyristor and prolong the service life of the soft starter , To improve its efficiency, but also to avoid the harmonic pollution to the grid. Soft starter also provides soft stop function, soft stop and soft start the process of reverse, the voltage gradually reduced, the number of revolutions gradually reduced to zero, to avoid free-wheeling caused by the impact of torque. How the frequency converter works

Q: 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

Q: How to disassemble the notebook power adapter: 3, then open the shell of the power adapter, you can see the adapter circuit outside the package with a copper shield, with a knife to cut the shielding tape on the tape, and then use the soldering iron shield and the internal circuit board connected to the two Solder joints, you can remove the shield.

Q: Is the laptop power adapter AC and DC?: Most laptop power adapters can be used for 100 ~ 240V AC (50 / 60Hz). Basically, most of the notebook computers are external power supply, with a power cord and the host connection, which can reduce the size and weight of the host, only a very small number of models built in the host power.

Q: Inverter 0.2KW, the motor speed requirements down to 4 turn, the motor pole 4 pole. Can the drive drive the motor?: The first calculation: 4-pole motor, rated 1450r / min divided by 50HZ, then it is 29r / HZ. Your request is 4r / min, then the frequency of the inverter must be 0.1 less than 0.2HZ without load are compared Difficult to achieve. You can do the test, then you can try to play, if used to produce what is the best or reducer, so the inverter and the motor are good.

Q: What is the meaning of the bipolar polarity in the inverter ah There is a +10V signal input is a -10V What is the meaning of ah?: Analog signal input: Reference setting Input voltage Positive terminal (0 --- 10V)
