    What is the role of automatic voltage stabilizer?-Discount automatic voltage stabilizer

    Date of issue:2022-04-11 General view:59

    The automatic voltage stabilizer is a device that stabilizes the output voltage. The automatic voltage stabilizer is composed of a voltage regulating circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit performs sampling, comparison and amplification, and then drives the servo motor to rotate, so that the position of the carbon brush of the voltage regulator changes, and the coil turns ratio is automatically adjusted to maintain the stability of the output voltage.


      automatic voltage stabilizer can be widely used in: electronic computers, precision machine tools, computed tomography (CT), precision instruments, test devices, Elevator lighting, imported equipment and production lines and other places that require stable voltage of the power supply. It is also suitable for users at the end of the low-voltage distribution network where the power supply voltage is too low or too high, and the fluctuation range is large, and the electrical equipment with large load changes, especially suitable for all voltage-stabilized electricity places that require high grid waveforms. High-power compensation type electric automatic voltage stabilizer can be connected to thermal power, hydraulic power and small generators.




      Automatic voltage stabilizer is a power supply circuit or power supply device that can automatically adjust the output voltage. Its function is to stabilize the power supply voltage that fluctuates greatly and does not meet the requirements of electrical equipment within its set value range, so that various circuits or electrical appliances can be stabilized. The equipment can work normally under the rated working voltage.


      With the rapid advancement of society, the number of electrical equipment is increasing day by day. However, due to the aging and development of power transmission and distribution facilities, as well as poor design and insufficient power supply, the voltage of end users is too low, while the voltage of line users is often too high. Sophisticated equipment, like a time bomb.


      As a public power grid, the mains system is connected to thousands of various loads. Some of the larger inductive, capacitive, switching power supplies and other loads not only obtain power from the power grid, but also cause damage to the power grid itself. Affect and deteriorate the power supply quality of the power grid or local power grid, resulting in the distortion of the mains voltage waveform or frequency drift. In addition, unexpected natural and man-made accidents, such as excessive load voltage, earthquake, lightning strike, open circuit or short circuit of power transmission and transformation system, will endanger the normal supply of electricity, thereby affecting the normal operation of the load.


      Unstable voltage will cause fatal injury or malfunction of the equipment, affect production, cause delay in delivery, unstable quality and other losses. At the same time, it accelerates the aging of the equipment, affects the service life and even burns the accessories, so that the owner faces the trouble of needing maintenance or needs to update the equipment in a short period of time, wasting resources; in severe cases, safety accidents even occur, resulting in immeasurable losses. Therefore, the use of automatic voltage stabilizer is essential for electrical equipment, especially high-tech and precision equipment with strict voltage requirements.
