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 are the main difference between electrical holding and magnetic holding in vacuum contactor?
In summary, the main difference between electrical holding and magnetic holding in a vacuum contactor is the method used to maintain the closed position of the main power contacts when the coil is de-energized. Electrical holding uses an external electrical circuit to provide continuous holding force, while magnetic holding relies on the energy stored in a permanent magnet to maintain the closed position without an external power supply.
