SCR Power Controller
An SCR (Silicon Controlled Rectifier) power controller is a semiconductor device that changes the voltage on the load by adjusting the trigger conduction angle of the output thyristor, thereby adjusting the output power and realizing the load voltage from zero to the applied voltage.

SCR Power Controller output Waveform
The SCR power regulator manufactured by Greegoo is an economical three-phase voltage regulator with phase output. It‘s control signal can be automatic 4-20mA, 0-5VDC, 0-10VDC, or manual potentiometer. The output is linear, meaning that as the control signal increases or decreases, the output voltage will increase or decrease accordingly.
SCR Power Controller control signal
The main difference in control methods between three-phase SSR (Solid State Relay) and three-phase SCR controller (Silicon Controlled Rectifier) is that SSR uses switch control, turning the circuit on or off to control the load, suitable for rapid switching operations, and is applied in simple switching scenarios like heater control. In contrast, SCR uses phase control, adjusting the conduction angle to precisely control the voltage and current of the load, suitable for scenarios requiring precise power regulation, such as motor speed control and light dimming. The control precision of SSR is reflected in its quick response and stability, while SCR can achieve higher control precision. The choice should be based on specific application needs.
SCR power controllers are widely used in heating equipment, lighting equipment, motor drive and speed regulation, as well as other industrial control fields, such as electric furnaces, stage lighting, water pump motors, and electroplating. They provide precise power regulation to meet the control needs of various equipment.
