STY-380D120F Voltage Regulating Module
With the support of three-phase synchronous transformer module TB-3, which is also internal working power supply, STY series three-phase AC voltage regulating module can be automatically controlled or manually controlled by external potentiometer without any external circuit and working power supply, so as to achieve stepless adjustment of three-phase load voltage from 0V to the full voltage of the grid by changing the thyristor conduction angle.
It is applied to 380VAC, 50HZ three-phase power grid. According to different control signals, it is divided into four types: E, F, G, H.
