Thyristorised Power Controllers

 

 
For the electrical heating system to control the temperature at the set point by switching contractors has many disadvantages, such as wear and tear, limited life of contractor, noisy operation. Besides these it has limited accuracy due to limitation of speed of operation, hence loss of power. All above mentioned disadvantages are eliminated by STC Thyristor Controller.

Applications

• All types of Electrical Heating Systems.
• Infrared Ovens.
• Vacuum Brazing Furnace.
• Continuos Annealing / Bell Furnace.


Salient Features
• From medium to higher capacity or single / three phase load
