III. Precautions (Must Read Before Use)

1. Induction heating generates a great deal of power during operation. In addition to heat generated by the PCB and electronic components, the heating coil also generates significant heat. To prevent the heating coil from burning out and affecting the entire system, be sure to use a cooling water pump for the heating coil;

2. Special care must be taken when using a switching power supply. High-power switching power supplies typically feature a soft-start function, meaning the output voltage rises gradually at the start. If the induction heating circuit is connected before the voltage reaches 11 V, the circuit will fail to oscillate due to insufficient voltage. This can cause both MOSFETs to conduct simultaneously, resulting in component burnout. Therefore, ensure the switching power supply voltage has stabilized before connecting the induction heating circuit. You may install a circuit breaker between the power supply and the mainboard, and wait until the switching power supply has stabilized before tripping the circuit breaker;

3. This circuit has very strict power supply requirements: a 12V power supply must be rated at over 500W, a 24V supply at over 1200W, a 36V supply at over 2000W, and a 48V supply at over 2600W (48V is the recommended operating voltage);

4. Regardless of the operating voltage, the circuit will not be damaged as long as the operating current remains below 50A; therefore, a 50A fuse can be installed to protect the circuit during high-power operation;

5. Heat generation is inevitable during high-power operation; therefore, a fan should be used to blow air upward for effective heat dissipation while the unit is running;

6. The operating voltage must never fall below 12V;

7. When the heater is operating, the heating coil generates a great deal of heat. Water cooling must be used to cool the heating coil to prevent high temperatures from damaging the mainboard;

8. The power supply input terminals are marked with positive and negative polarities; do not reverse the connections!

9. The heating coil may become deformed during shipping, causing a short circuit between layers. Please separate the layers before connecting them to the mainboard; otherwise, an overload may occur, burning out the mainboard.

10. Never power on the unit without a load (here, “no load” means the output is not connected to any load; connecting the heating coil without a heating object does not count as no load). Otherwise, the board will emit a high-frequency noise, instantly burn out the motherboard, and render it completely unusable!
