Q:Inverter signal line analog 4-20mA connection positive and negative can be reversed?
Theoretically reverse seems to be possible, but the operation will be normal, you can do experiments to try what is the result. Various manufacturers of the inverter may be the treatment of this problem will be different.
Q:ASUS and dell notebook power adapter can be universal?
One, not necessarily interchangeable. Need to compare the two adapter specifications to determine: 1, the books power adapter, there are 90W and 60W of the other, some products output voltage 19V and 14V of the other. "General" conditions, as long as the output power of the adapter is the same, the output voltage is the same (current may not consider), that is, their specifications are the same, you can directly substitute. 2, however, some foreign imports of products using 110V AC products, be careful to see clearly. 3, before the use of replacement, pay attention to observe if connected to the books of the power plug specifications are different, you can not directly insert. An interface adapter can be purchased. Can also be bad adapter plug, cut into the replacement adapter; Second, for example: 1, LITEON OEM products, parameters: input AC 100 ~ 240V 1.5A, output DC 19V3.42A. Rated output power 60W; 2, ASUS books supporting products, parameters: AC 100 ~ 240V 1.5A, output DC 19V 4.74A. Rated output power 90W.
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
Q:What is the difference between the electronic governor and the frequency converter on the motor speed regulation?
Electronic governor is for single-phase motor, by changing the access winding resistance and capacitance to adjust the motor speed, the speed of the power supply power for the output does not change, so this speed is not an energy Type of speed control methods, such as home for the use of fans and the like. Inverter speed is the original direct input three-phase asynchronous motor power first access to the inverter, in the inverter through the PWM and other electronic converter technology to rectify the frequency AC, inverter, become a frequency controllable AC In the input to the motor, in the motor running through the V / F control, output torque control, vector control and other control methods to adjust the frequency, change the loop current, to achieve energy-saving operation, especially in the light load energy efficiency is obvious, An energy-saving products that have been widely promoted and applied
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
Q:Is it possible to use a different laptop's power adapter?
For the power adapter, whether access to equipment, the following aspects of the measurement standards: Interface form The interface plug and socket used must be dimensioned. Voltage size The output voltage of the adapter is the same as the required voltage of the connected device (eg notebook). Inconsistencies may not be able to start or burn the device properly. Current or power The power of the adapter is greater than the maximum power required by the device. Power is not enough, may cause the voltage to drop, the adapter is hot, or burn the adapter. More than the above, the use of more power of the power adapter, while meeting the interface and voltage conditions, it can be replaced.
Q:Three-phase asynchronous AC motor speed control method
Second, the frequency control method Frequency control is to change the frequency of the motor stator power supply, thus changing its synchronous speed control method. Frequency converter system can be divided into AC - DC - AC inverter and AC - AC inverter two categories, most of the current domestic use - cross - frequency converter. Its characteristics: High efficiency, no additional loss during the speed control process; Wide range of applications, can be used for cage type asynchronous motor; Speed ​​range, the characteristics of hard, high precision; Complex technology, high cost, maintenance and repair difficult. This method is suitable for applications requiring high precision and better speed performance.
Q:55 瓩 4 pole motor with a frequency of one hour can save much electricity
It depends on what type of equipment you use, the average energy-saving fan pumps, about 25-40 between; generic class is based on the frequency you use to decide, according to the frequency you use with 50 Hz Compared to energy saving.
Q:My motor is a low frequency 8 pole motor, about 80W. I would like to choose a frequency converter
Poor match, the program is unreasonable Current 1.5A, choose a single-phase 220v power supply, 370-500w inverter it
Q:Yaskawa inverter reported base blockade what is the reason?
This is the base block command, when the external input block command signal, the inverter will appear this code, the code appears, the motor will be free to rotate, does not affect the use.
