Product description

TNS (SVC) series automatic Three-phase AC voltage regulator is composed of voltage regulator circuit, control circuit, and servo motor. The control circuit samples and amplifies the voltage signal and then controls the servo motor to drive the arm and the brush to rotate in the desired direction so that the output voltage is adjusted to the rated value to achieve the purpose of voltage regulation. Performance indicators fully comply with JB/T 10089 standard.
TNS Series (SVC) series of high-precision automatic Three-phase AC voltage regulator has a beautiful appearance, small size, light weight, low power consumption, a variety of protection functions, stable and reliable, the output waveform distortion is small. Can be widely used in industrial production, scientific research, medical and health, household appliances and other power grid voltage fluctuations or large changes in the grid voltage season, can provide high-quality power to any load.
