Three: Note (must see before use)
1. Induction heating work is very powerful. In addition to the heating of the PCB board and electronic components, the heating capacity of the heating coil is also very large. In order to avoid the burning of the heating coil and affect the whole system, please be sure to support the heating coil cooling water pump;
2. It is necessary to pay attention when using the switching power supply, because the high-power switching power supply generally has a slow-start function, that is, it slowly rises when the output voltage starts, and if the voltage rises to 11V, the induction heating circuit is turned on because of the voltage. Not enough, the circuit does not vibrate, so that the two MOS tubes are turned on at the same time to burn the components. Therefore, it is necessary to connect the induction heating circuit after the switching power supply voltage is stable, and an air switch can be connected between the power supply and the main board. After the electricity is stable, push it again;
3. This circuit has strict requirements on power supply. The 12V power supply must use more than 500W power supply, 24V is greater than 1200W, 36V is greater than 2000W, 48V is greater than 2600W (recommended working voltage is 48V);
4. No matter whether it is used under any voltage, as long as the working current is lower than 50A, it will not burn the circuit. Therefore, a 50A fuse can be added to protect the circuit during high-power operation.
5. It is inevitable that high-power operation heat is generated. Therefore, the fan should be blown to effectively dissipate heat while working.
6. The working voltage must not be lower than 12V;
7. When the heating machine is working, the heating coil will generate high heat. The water cooling must be used to cool the heating coil to avoid damage to the main board caused by high temperature.
8. The input end of the power supply is marked with positive and negative poles. Do not reverse the connection!
9. The heating coil may be deformed during transportation, resulting in a short circuit between the layers. Please separate the motherboard and connect it to the motherboard. Otherwise, overload may occur and the motherboard may be burned out.
10. Do not power on at no load (here, the no-load refers to the output without any load, and the heating coil does not heat the object is not empty), otherwise the board will emit a very high frequency noise, instantly burn the motherboard, completely scrapped!
【pay attention】
[1] The power of induction heating is very large. In addition to the heat generated by the board and components, the heat generated by the copper tube is also very large. Buyers can bring their own water cooling system, you can buy a small water pump and a rubber hose with an inner diameter of 4mm or 2mm; you can also purchase the matching water pump in the package.
[2] It must be noted when using a switching power supply, because a high-power switching power supply generally has a slow-start function, that is, it slowly rises at the beginning of the output voltage, and if the voltage rises to 10V, the induction heating circuit is turned on because If the voltage is not enough, the circuit will not vibrate, so that the two MOS tubes will be turned on at the same time to burn the components. Therefore, it is necessary to connect the induction heating circuit after the switching power supply voltage is stable; an air switch can be directly connected to the main board and the power supply.
[3] When heating metal objects, try not to heat the metal with too much volume. Otherwise, the overload may occur due to power overload. It is better to add a 50A fuse or ammeter and air switch when using. Match.
[4] Although this driver board can withstand more than 50A current, it is recommended not to exceed 48V55A in order to prevent accidents and damage for long-term continuous operation.
[5] The heating coil of the package has a diameter of 60mm and a design voltage of 86V. If a voltage of 40V or more is used, a heating coil with an inner diameter of 60mm or more must be used. The pump uses a 12V DC power supply. Please use a voltage regulator module to supply power separately to avoid burning the fan. Water pump.
[6] For induction heating, the copper tube in the package of this product should be used, or it should be wound according to the standard of 10 mm inner diameter of 60mm, otherwise the buyer will bear the responsibility for any burning problem.
[7] This heating module is designed to be used in environments above 2000W. If the working power is low, you can buy the 1800W induction heating machine in this shop, which is relatively cheap.
