CD Automation has developed many applications dedicated to drive particular loads and one of these application is for Silicon Carbide.
The Philosopy is to use standard Thyristor units with serial communication and to implement the control strategy inside the intelligent panel.

This Touch Panel in addition to a CD Automation universal unit able to work with all firing and control mode removing all application risks due to the control type selection

• The Thyristor Units are standard and easy to be found everywhere
• An external port is available to connect your normally used PLC
• One Ethernet port is available on 8” touch panel

The Human interface is friendly and just feeling few data of thermic project is possible to achive two different modes to drive SIC: Burst Firing with automatic adjustment of Power Limit Or Phase Angle with transfer from voltage to Power Control Mode.

• Automatic configuration and tuning of the thyristor unit
• Automatic tuning of Power Control mode VxI
• Message on when to change the elements because are at the end of their life
• Automatic switch from Voltage to VxI control mode when the element temperature is the correct one
• Automatic tuning procedure of Heather break alarm to diagnostic partial or total load failure
• Diagnostic of fuse failure and Thyristor in short circuit
• Recent and Historical Curve of following process variable
• Power density W/Cm2
• Load Voltage
• Load Current
• Power to the load
• Resistance value curve with element new
• Time elapsed from start to actual resistance value

All in line with SANDVIK specifications for a long element life. Real time clock for furnace maintenance.
These touch panel is available with different features:

• Model 5″ in black and white
• Model 5″,8″,10″and 12″ in colour
