Our SCR Power Controller offers precise power and temperature regulation, making it ideal for various industrial applications. Designed with flexibility and reliability in mind, it supports multiple control modes:

  • Constant power control
  • Constant current control
  • Open loop control
  • Cycle zero crossing control

To ensure safe and efficient operation, the controller includes the following protective features:

  • Power supply phase loss protection
  • Radiator overheat protection
  • Load overcurrent protection
  • Three-phase current unbalance protection

The device is equipped with an LCD display for real-time monitoring, allowing easy customization of parameters. Input methods such as 4-20mA, 0-5V, 0-10V, and potentiometer control are supported, ensuring seamless integration with PLCs and other systems.

For effective heat management, each unit comes with dual DC fans and radiators, guaranteeing optimal performance and extending the lifespan of the controller. The energy-saving constant temperature control reduces power fluctuations and enhances operational efficiency.

For loads like silicon carbon rods or heaters, this controller provides excellent performance, ensuring safety and efficiency in your operations. The operation panel can also be extended with a lead-out cable for easy integration into your specific setup.

Wiring Diagram

Here’s how you can connect our SCR power controllers based on different control signals. Each control method is designed for ease of use and ensures efficient and safe power regulation for your heating systems:

  • Control Signal: 4-20mA
    This is one of the most common methods for regulating heating power. For detailed instructions on how to connect the SCR power controllers with a 4-20mA temperature controller, please refer to our blog on 4-20mA control signal connection.
  • Control Signal: 0-5V / 0-10V
    If you are using a DC voltage signal (0-5V or 0-10V) to control heating power, our controllers support this input. For the wiring details, check our guide on using DC voltage inputs.
  • Control Signal: Potentiometer
    A potentiometer can also be used to adjust the heating power. Learn how to wire the SCR power controllers with a potentiometer as an input signal in our potentiometer control wiring guide.

Human-Machine Interface

AIGOODELE SCR power controllers feature a user-friendly HMI with a clear LCD display that allows easy monitoring of real-time status and quick adjustments. Parameters such as control modes, output power, and protection settings can be configured directly from the display. Designed for simplicity, the interface provides precise control over heating applications, making it easy to operate. For more details, check out our Operation Interface of SCR Power Regulator.
