SCR Power Controllers
HC Thermal offers a line of SCR power controllers to complement our product portfolio, broadening our ability to service customers' unique process heating applications. With several types available, we offer zero-cross SCRs to complement resistive loads or electric process heaters.
Compared to phase angle, zero-cross produces the least amount of harmonics and feedback into the power grid providing precise control. Our SCRs coupled with a reputable PID loop temperature controller will provide excellent proportional control with the desired accuracy and turndown needed for your project’s process control. These controllers are used in applications when a device in need of high power and high control is demanded.
Benefits of SCR Power Controllers
Silicon-controlled rectifiers, also known as SCRs, are vital to temperature regulation in heaters. Their primary role is to control the flow of electricity from the power grid to the heater. SCR Power Controllers are efficient, reliable, and long-lasting.
SCRs are used in many applications due to their role in several industrial manufacturing processes, including the chemical industry, metals industry, and oil and gas industry. Similar to many of our electric process heaters, the SCR Power Controller is versatile in use.
Other benefits include:
- A wide range of operation modes and options for communication
- Seamless integration
