It operates on SCRs (thyristors). One of its most common applications is temperature control of electric heaters through power regulation, using a digital process controller with a 4–20 mA control output and a thyristor power regulation system (TPR). With these components you can achieve proportional control of heater power through the voltage modulation the system performs. This system can also be applied to ON-OFF control through a relay output on a temperature controller. Thyristor power regulation systems have three-phase and single-phase applications, for both resistive loads (electric heaters) and inductive loads (motors)
