Greegoo SCR Power Controller: The Ideal Choice for Industrial Applications
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
These SCR power regulator are available in current ranges from 60A to 1000A and are assembled with suitable heat sinks and cooling fans. Solid state relays can also be used in thermal control applications, but this voltage controller is better suited for heavy loads compared to our three-phase SSRs.
Applications of SCR power controllers include:
- Heating equipment: electric furnaces, ovens, heating equipment, injection molding equipment, textile equipment, drying systems
- Lighting equipment: stage lighting, hotel lighting, industrial lighting, public lighting
- Motor drive and speed regulation: fan motors, water pump motors, torque motors
- Other industrial controls: transformers, inductors, electroplating, welding.

What is the main difference between 8/20μs and 10/350μs in SPD?
8/20μs: Suitable for protection against fast-rising and short-duration surges, such as lightning strikes and rapid switching events.10/350μs: Suitable for protection against slower-rising and longer-duration surges, often associated with power distribution network switching operations and industrial electrical systems.
