The three-phase AC phase shift voltage regulator is designed with an imported large-scale integrated circuit, which integrates a three-phase phase shift trigger circuit, one-way thyristor, RC resistance capacitance absorption circuit, and power supply circuit. It can be adjusted automatically or manually to change the voltage on the load, thereby adjusting the three-phase output power. That is, under the input control, a strong trigger pulse signal is generated that can change the conduction angle of three phases, and then the internal thyristor is controlled separately to achieve stepless adjustment of the three-phase load voltage from 0V to the full voltage of the power grid.

It can be widely used in small current heating control situations such as electric heating power control, dimming, transformer primary voltage regulation, and so on.
