The high-precision fully automatic voltage regulator produced by Weixin Electric is an intelligent digital display voltage regulator. The product has multiple functions such as self inspection during startup, overvoltage and undervoltage protection, long and short delay selection, over temperature protection, over-current protection, etc. It has the characteristics of waveform distortion free, reliable performance, and long-term operation.
The TNS (SVC) series single-phase high-precision fully automatic AC voltage regulator is one of our company’s leading products. Its structure consists of a contact type autotransformer, 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, adjust the position of the autotransformer carbon brush, and adjust the output voltage to the rated value and reach a stable state.
This series of voltage regulators is a common type, with advantages such as a wide variety, complete specifications, and beautiful appearance. It has waveform distortion free, reliable performance, and can last for a long time.
