Compared with our common resistors, the structural characteristics of our varistors are different. The structural characteristics of varistors are

With its own characteristics, varistor is manufactured according to the nonlinear characteristics of our semiconductor materials.

Our common resistors need to follow certain rules of Ohm's law, but the varistor is special due to its own voltage and current.

This layer of nonlinearity does not require full compliance with Ohm's law. The voltage across the varistor is much smaller than the nominal

When the voltage value is reached, the resistance value of the varistor is completely close to infinity. It can be said that there is no current through the inside of the varistor.

On the contrary, if the voltage across the varistor is much greater than the nominal voltage, our varistor will quickly break down.

The conductor, and then the high-resistance working state is converted into a low-resistance working state, and the operating current of the varistor is also sharply increased.

. If the voltage across the varistor is much lower than the nominal voltage of the varistor, the high resistance of our varistor

The working state can be restored again, but if the voltage across the varistor is far beyond the limit of the maximum value of the varistor

When pressed, the pressure sensitive device will be completely damaged and breakdown, which is unrecoverable by the varistor.

Varistors are widely used in the electronic power industry, such as our home appliances and other electronic industries.

To over voltage protection, lightning protection, surge protector, absorption pulse, limiting, noise cancellation, protection of semiconductor components and so on.

Person can control the curtains open or close with switch.

Electric curtain machine consists of three parts:

1. Intelligent control system for controlling the opening and closing of curtains.
2. Operate and set the main controller of the wireless controller. (electric curtain)
3.Pulling the curtain actuator motor and pulling mechanism. The host machine controls the positive and reverse rotation of the motor, and the curtain is automatically closed or opened by a pulley.
It can make the infrared remote control the curtain open or close the directly,setting up the main controller automatic function with remote control, once set up and open the automatic control function, the main controller will automatically control function according to it.
