High Frequency Induction Heating Equipment Metal Hot Forming And Heat Treatment Equipment

Overview of high frequency induction heating equipment:

The high-frequency heater adopts a series resonance circuit, and the circuit structure is as follows: after resonance, the high-frequency power supply with low voltage and high current is output through the high-frequency transformer; 15kw and 25kW equipment are * products of our company. MOSFET power devices are used for 15kw power and IGBT power devices are used for 25kW power. The inverter control technology of our company is adopted. The equipment structure is very simple, the reliability is high, the maintenance rate is low, and it is convenient for customers to maintain by themselves. It is one of the most widely used equipment at present
