What is the frequency of induction heating equipment? How to adjust the heating depth?

hat is the frequency of induction heating equipment? How to adjust the heating depth?

The power frequency of induction heating equipment has four levels:

1. Below 500Hz is called low frequency power supply

2. The range of 1-10KHZ is called intermediate frequency induction heating power supply, and the depth of intermediate frequency induction heating is 3-6mm

3. In the range of 15-50KHz, it is called super audio frequency induction heating power supply, and the depth of super audio frequency induction heating is 1.5-4mm

4. The range of 30-100KHz is called high-frequency induction heating power supply, and the depth of high-frequency induction heating is 0.2-2mm
