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:The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!
1. submersible pumps are generally the problem, far away from the reflection voltage, the pump insulation breakdown, in particular, to better pump.
2. Distance away, the inverter and pump connection thicker.
3. Then on the output filter.
Q:On the laptop power adapter problem
Can be simply calculated; 19 * 4.74 = 90.06 90W
19 * 3.42 = 64.98 65W
Obviously, the second is a virtual standard, can not be used
It is not enough power, ranging from the adapter burned, while the motherboard is like other notebook hardware damage, unpredictable.
The adapter is likely to burn after the high and low voltage to the notebook board burned the situation more common.
My notebook is dell original 4.62A, when playing the game are very hot.
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:A water supply project, how to choose electrodes and frequency converters, such as giving a 7-storey water supply
1. Select the pressure pump head: 7 * 2.5 (3) = 17.5 (21) meters; this is the number of theory, in fact, should be selected 40 meters, (0.4Mpa).
Q:Is the number of Amps of the notebook power adapter higher than the original number of security on the computer?
Sure answer, no! Rest assured with it, but be careful not to buy the cottage goods, this on the computer and security is not good. good luck!
Q:How to make the motor speed (control speed), can not use frequency
In general, the torque generated by the motor is reduced with decreasing frequency (decrease in speed), and the reduced actual data is given in some frequency converter manuals. By using the flux vector control of the inverter, will improve the motor at low speed torque, even in the low speed area motor can also output enough torque. When the frequency converter to speed up to 60Hz frequency, the motor output torque will reduce the normal motor is designed to 50Hz (60Hz) voltage, the rated torque is given in this voltage range. So the rated frequency under the speed is called constant torque speed, the inverter output frequency is greater than 50Hz frequency, the motor torque to be inversely proportional to the frequency of the relationship between the decline. When the motor is running at a frequency greater than 60 Hz, the magnitude of the motor load must be taken into account to prevent the motor output torque from being insufficient. For example, when the torque generated by the motor at 100 Hz is about to be reduced to about 50 Hz, the torque is generated. So the rated frequency above the speed is called constant power speed.
Q:Can the laptop's power adapter be used for years?
Generally 3 to 5 years is not a problem, good quality can be used for 10 years.
Power adapter is a small portable electronic equipment and electrical and electronic power supply conversion equipment, generally by the shell, power transformer and rectifier circuit, according to its output type can be divided into AC output and DC output type; by way of connection Divided into wall and desktop. Extensive support in the phone son machine, game consoles, language repeaters, Walkman, notebook computers, cellular phones and other equipment.
Q:Octopus AC Servo motor can be driven with ordinary inverter?
If it is asynchronous motor, then take the power, voltage matching ordinary inverter drive no problem, you only need to enter the appropriate parameters, such as current, power size and other parameters, and then off-line parameters from the adjustment (if the vector control run), you can run
Q:What is the IGBT? Our inverter IGBT fried,
Popular point is a switch, give him the signal to continue in accordance with a certain order switch, the DC through the switch into a change in the exchange of alternating current, different frequency.
