The SVR series single-phase high-precision automatic AC voltage stabilizer is composed of a contact auto-voltage 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，Adjust the position of the carbon brush of the auto-voltage regulator to adjust the output voltage to the rated value and reach a stable state.
TVR series three-phase high-precision automatic AC voltage stabilizer, a new generation of intelligent regulated power supply, the input phase system is three-phase four-wire system, the output voltage is 220Vac phase voltage and the line voltage is 380Vac. Within the rated capacity range, it can be used at the same time for electrical equipment with a single-phase 220Vac or three- phase 380Vac power supply, and is equipped with delay, over voltage, under voltage, and over current protection functions.
