Working principle of thyristor controller

The thyristor controller achieves precise temperature control by precisely controlling voltage, current, and power. And with its advanced digital control algorithm, it has played an important role in optimizing the efficiency of electricity usage and saving energy.

Js3000 @ thyristor controller is a device that adjusts and controls the electrical power according to the process temperature during the electric heating process. The temperature of the heated medium is input to the regulating instrument (PID temperature controller) or PLC or DCS through a temperature sensor. After PID calculation or characteristic temperature algorithm, the control signal (analog signal or bus signal) is output to the power regulator as the set value for adjustment. The regulator adjusts the heating power according to the set value, thus achieving high and low temperature regulation control.
