Q:How does the spindle drive system of the inverter realize the positive and negative control of the main pole?: The general inverter has an external terminal control and communication control two modes optional, select one of them can be completed ah

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)

Q:380V 2 pole motor can use the inverter?: Special attention, variable frequency motor with the ordinary different, easy winding film damage

Q:Pump frequency converter instantaneous restart and restart the problem: Speed tracking start, with them better. Speed search time is less than the free downtime, not too small too much, will be over-voltage protection. I do not understand and contact me. Your inverter voltage level, manufacturers.

Q:What is the frequency of `30 points: Frequency is to change the frequency ah, see what you are variable frequency equipment.

Q:380V motor addition to the inverter, but also how to change its speed?: Use the star connection to reduce the speed by changing the torque

Q:How to choose the inverter: and you need to know how The use of frequency converter, as well as voltage 380, are fixed, and the frequency can be changed

Q:Lenovo g450 laptop power adapter specifications is what?: Lenovo G450 power adapter Model: ADP-90RH B LENOVO P / N: 36001681 Input: 100-240V ~ 1.5A 50-60Hz Output: 19V $ 4.74

Q:What are the differences and links between the soft starters and the frequency converters, and their respective principles and uses?: The soft starter is activated by adjusting the voltage and current, and the frequency converter starts the motor by changing the frequency of the power supply. The soft starter can theoretically smooth and gradually start the motor to the maximum speed. No impact current (ordinary start-up current is 6-7 times the rated current) The inverter is best suited for tap water and fans, etc. The soft starter is not suitable for everything except for heavy load start.

Q:How to choose a power adapter: There are several principles for replacing the power adapter. 1. The voltage is the same or similar. Your computer's nominal input voltage is 16V, and the following adapter's rated output voltage is 20V, the difference is large, can not be replaced, may damage the computer. 2. The plug has the same polarity. Your notebook marked on the polarity of the mark is inside and outside the negative, that the adapter I really can not see what is the polarity of the label, you take a closer look if the symbols and notes on the notebook is not the same, it is absolutely not. 3. The rated output current of the power adapter can not be less than the rated input current of the computer. Your computer marked the maximum input current is 3.36A, then you buy the power adapter when you want to buy the output current greater than or equal to 3.36A, the bigger the better, but the greater the output current that the greater the rated power, too much Waste, and very cumbersome, generally slightly larger than on the line, leaving some margin.
