manual tension controllers, manual, semi-automatic and fully automatic tension controllers.
Manual tension controller, but modern gravure press manual tension control system has been basically eliminated. The main circuit of the automatic tension controller uses PWM constant current switch to replace the conventional bulky transformer power supply circuit, so it has the characteristics of light weight, small size, high constant current accuracy, etc., the controller operation panel adopts micro-touch switch to make the operation simple, and the output current adopts LED digital tube to make the display more intuitive.
The selection of tension controllers is also based on their classification.
