Application: The main control board is an important part of the control system. The main working principle of the control system: through the sampling of the inverter voltage, inverter current, induction coil voltage, and electric heating capacitor voltage, the output power of the inverter is adjusted and controlled by the calculation of the main control board.
1. Stable operation: All electronic components on the main control board are selected from internationally renowned brands, and are selected according to high temperature grades, so the main control board has very high stability.
2. High power output accuracy: All important data of the main control board are taken from the precision power supply of AD company in the United States for reference. The power output accuracy is high, and the error is less than 1%.
3. Diversity of control modes: The main control board has two control modes when controlling the power supply: constant power control mode and constant voltage control mode (not described below). This design truly realizes the constant power control of the intermediate frequency power supply.
4. The main control board has a perfect double protection mechanism: such as:
Main circuit phase loss protection
Main circuit short circuit protection
SCR overvoltage protection
Cooling water over temperature protection
Cooling water pressure is too low protection
Earth/leakage protection
In addition to these protection systems, the following extreme limits are set:
a. Full power limit
b. Capacitor voltage limit
c. Induction coil voltage limit
d. Output current limit
e. Frequency limit
f.T.O.T. Limit
These protection systems and limit limits ensure that the induction melting system works safely and reliably.
