The electromagnetic heater is a high-performance device designed with advanced technology and multiple safety features to ensure reliable and efficient operation. Below is an overview of its key components and the 16 safety protections it offers. 1. **Heater Chassis**: The chassis features a dustproof design that protects internal circuits, significantly extending the service life of the unit. This ensures long-term stability in various environments. 2. **IGBT Temperature Sensor**: A high-precision thermistor (70°C) is used, along with imported thermal grease, to efficiently transfer heat from the IGBT module. This helps maintain safe operating temperatures and prevents overheating. 3. **Cooling Fan**: A brushless AC fan is employed, offering higher airflow and a lifespan of up to 20,000 hours. It also operates quietly, with noise levels below 45dB, ensuring a comfortable working environment. 4. **Power Supply**: The system uses a high-performance switching power supply, which improves energy efficiency and reduces power loss during operation. 5. **IGBT Module**: Equipped with top-tier Infineon modules, these IGBTs are known for their fast response, high voltage resistance, high current capacity, and excellent stability, making them ideal for demanding applications. 6. **Heat Sink**: Designed in-house, the heat sink effectively dissipates heat, ensuring the circuit remains within safe temperature limits even under heavy load. 7. **High-Voltage Capacitor**: This component is built for high voltage, high frequency, and low loss, contributing to the overall efficiency and reliability of the system. **Biyuanda Electromagnetic Heater: 16 Safety Features** 1. **Overcurrent Protection**: If the current exceeds the rated value, the heater automatically reduces the current or stops heating to prevent damage. 2. **Overvoltage Protection**: When the three-phase voltage exceeds 450V, the heater stops working, displays a fault code on the digital screen, and sounds an alarm. 3. **Undervoltage Protection**: If the voltage drops below 330V, the heater halts operation and alerts the user with a fault code and alarm. 4. **Short Circuit Protection for Heating Coil**: In case of coil short circuit or open circuit, the heater stops and shows the corresponding error code. 5. **Short Circuit Protection for IGBT Module**: If the IGBT module experiences a short circuit, the heater immediately stops and triggers an alarm. 6. **Open Circuit Protection for IGBT Module**: If the IGBT module is open, the heater will stop and display a fault code. 7. **IGBT Overheat Protection**: When the IGBT module gets too hot, the heater stops and warns the user with an alarm and code. 8. **IGBT Overcurrent Protection**: If the IGBT current becomes too high, the heater will shut down and alert the user. 9. **Overheat Protection**: If the internal temperature rises rapidly due to a faulty fan or IGBT overheat, the heater stops and displays a fault code. 10. **Waterproof and Moisture Protection**: The control board is treated to resist water and moisture. If water enters, after cleaning, the heater can automatically resume normal operation. 11. **Surge Protection**: During power surges, the heater stops heating immediately and resumes after the surge subsides. 12. **Anti-Dry Protection**: When the barrel reaches the Curie point, the heater stops heating and alerts the user. 13. **Lightning Protection**: During lightning strikes, the heater temporarily stops to protect itself and resumes once the interference is gone. 14. **Leakage Protection**: If external leakage is detected, the heater stops and cuts off the power supply, displaying an error code and sounding an alarm. 15. **Phase Loss Protection**: If one or two phases of the three-phase input are missing, the heater stops heating. 16. **No Load Protection**: If no load is detected, the heater automatically powers off and stops working to prevent unnecessary energy consumption. With these advanced features, the Biyuanda electromagnetic heater ensures both performance and safety, making it a reliable choice for industrial and commercial applications.
