Introduction To Automatic Voltage Regulator

A device used to reduce the impact of various interferences on national income in the economic system itself. Also known as an internal voltage stabilizer, it refers to a mechanism that exists in the economic system itself to reduce the impact of various interferences on national income. It can automatically suppress inflation when the economy is prosperous and automatically alleviate depression when the economy is in recession, without the government taking any action. Automatic Voltage Regulator, its structure consists of a contact auto-coupling regulator, a servo motor, an automatic control circuit, etc. When the grid voltage is unstable or the load changes, the automatic sampling control circuit sends a signal to drive the servo motor to adjust the position of the carbon brush of the auto-coupling regulator so that the output voltage is adjusted to the rated value and reaches a stable state. The three-phase high-precision fully automatic AC voltage stabilizer is a combination of the performance of the SVC series single-phase products. Its input phase system is divided into three-phase four-wire system, and the output voltage is line voltage 380V within the rated capacity range. It can be used for power supply voltage of three-phase 380V electrical equipment at the same time, and has an overvoltage protection function. SVC (TND, TNS) series voltage stabilizers are ordinary types with many varieties, full specifications, and beautiful appearance. It has the characteristics of no waveform distortion, reliable performance, long-term operation, etc. It is equipped with overvoltage protection function. According to user needs, undervoltage, delay and other protection functions can be set.
