FAQ

Does the teacher know the working principle of the inverter?

The frequency converter is an AC-DC-AC power electronic device that converts 50 Hz AC sine wave into straight high voltage direct current and then converts it into an AC power that can control the voltage and frequency, driving the three-phase AC motor.

ABB frequency converter and the difference between domestic frequency converter

Optical microscope mainly by the eyepiece, objective lens, stage and mirror composition.

Is the laptop power adapter long-haul?

This is not good, If you need to shut down, then it is recommended that the power adapter plug from the board to pull down. Because if only pull the adapter and the computer plug so that the adapter will still have the internal current through, hear the small sound is actually the sound of the current. So it is recommended that the power adapter from the outlet on the unplugged, and the computer connected to the one do not have to pull, so that will not cause the power adapter power and convenient computer to open.

Abb inverter s510 with water circulation pump why the motor fever. The motor is 2 pole

Whether the motor is abnormal roar, if any, you can adjust the inverter parameters in the motor carrier frequency

Notebook power adapter on how to look at power

then the same formula can be used to calculate: power (unit: W) = voltage (unit: V) × current (unit: A). For example: the power adapter only identifies the output voltage is 20V, the output current is 4.5A, then we set a formula to know the output power is 20 × 4.5 = 90W.

Asus notebook power adapter how to open

if the power adapter is broken directly to the computer with a city on the line can not spend a few money back you can burn the computer is bigger to go to the computer The city took to repair and no one to repair to buy a very low price

Laptop power adapter is broken, which brand is better domestic

I suggest to buy a compatible adapter on it, because My HP is the power adapter is broken, I spent more than 20 yuan to buy a city, the normal use of more than a year did not find the problem.

How do I select a drive? Which brand is better

?11, the inverter drives the synchronous motor, compared with the power frequency power regulator, reduce the output capacity of 10% to 20%, the inverter's continuous output current is greater than the synchronous motor rated current and synchronous pull the current value of the unit value product. ????12, for the compressor, vibration and other torque fluctuations in the load and the hydraulic pump and other peak load case, if the motor in accordance with the rated current or power value of the inverter, then there may be due to peak current over-current protection Action phenomenon. Therefore, you should understand the frequency of the operation of the situation, select the maximum current than the maximum current output of the inverter. When the inverter drives the submersible pump motor, the rated current is greater than the rated current of the submersible pump motor because the rated current of the submersible pump motor is greater than the rated current of the normal motor. ????13, when the inverter control Roots blower, because of its large starting current, so select the inverter must pay attention to whether the capacity of the inverter is large enough. ????14, select the inverter, be sure to pay attention to whether the protection level with the scene to match. Otherwise the scene of dust, water vapor will affect the long-term operation of the inverter. ????15, single-phase motor is not suitable for inverter drive.
