SCR Power Controller
An SCR power controller is a controller built around a dedicated control circuit that triggers thyristors (SCRs) to adjust the power of AC loads. It is also called a thyristor power controller, SCR regulator, SCR voltage regulator, power regulator, or power controller.
By firing method it divides into voltage regulation and power regulation. Voltage regulation uses phase control; power regulation has fixed-cycle and variable-cycle methods.
Widely applied in:
- Electric furnace industry: annealing, drying, hardening, sintering, crucible, tunnel, melting, box, pit, roller, vacuum, bogie-hearth, aging, bell, atmosphere, experimental furnaces; heat treatment, resistance furnaces, mesh-belt furnaces, high-temperature furnaces, kilns.
- Machinery: packaging, injection molding, heat-shrink, extrusion, food machinery, tempering equipment, plastics processing, infrared heating.
- Glass industry: glass fiber, glass forming, glass melting, glass printing, float-glass lines, annealing lehrs.
- Automotive: paint drying, thermoforming.
- Energy-saving lighting: tunnel lighting, street lighting, studio lighting, stage lighting.
- Chemical industry: distillation and evaporation, preheating systems, pipeline heating, petrochemicals, temperature compensation.
- Others: salt-bath furnaces, line-frequency induction furnaces, hardening-furnace and heat-treatment temperature control, diamond-press heating, high-power magnetizing/demagnetizing equipment, aviation power-supply regulation, central air-conditioning heater control, textile machinery, crystal production, powder-metallurgy machinery, metallurgical machinery, petrochemical machinery, smooth lamp dimming, and constant-voltage / constant-current / constant-power control.
