The HB-SW series three-phase high-precision fully automatic AC voltage regulator is a combination of single-phase series high-precision fully automatic AC voltage regulators. The input of the power grid is a three-phase four wire system, with a star (Y-shaped) connection method. The output is also a three-phase four wire system, with three ammeters indicating the output current of each phase, and a switching switch and a voltmeter shifting to monitor the line voltage.

This instrument has the characteristics of small size, light weight, low output waveform distortion, reliable performance, and long-term operation. It is equipped with overvoltage protection function, and can be equipped with undervoltage, delay and other protection functions according to user needs. It can be widely used in any electric field and is an ideal voltage stabilizing power source.

1、 Product IntroductionThe HB-SW series three-phase high-precision fully automatic AC voltage regulator is composed of contact autotransformer, servo motor, automatic control circuit, etc. When the voltage of the power grid is unstable or the load changes, automatic sampling is carried out, and the control circuit sends a signal to drive the servo motor, adjust the position of the carbon brush of the self coupling voltage regulator, and adjust the output voltage to the rated value and reach a stable state.
