5. The maximum temperature of direct heating of metal iron within 20mm diameter is 1200 degrees Celsius, and the maximum temperature of heating iron with standard 60mm diameter heating ring is about 1000 degrees Celsius;

6. The maximum temperature of the crucible is 1600 degrees Celsius, which can melt iron, gold, silver, aluminum, copper and other metals;

Three: Precautions

1. The power of induction heating is very high. In addition to the heat generated by the PCB board and electronic components, the heat generation of the heating coil is also very large. In order to avoid the heating coil burning and affecting the entire system, please be sure to match the heating coil cooling water pump;

2. Care must be taken when using switching power supplies, because high-power switching power supplies generally have a slow start function, that is, the output voltage rises slowly at the beginning, and if the induction heating circuit is turned on before the voltage rises to 11V, it will be due to the voltage. If it is not enough, the circuit will not vibrate, so that the MOS tubes on both sides will be turned on at the same time and the components will be burned. Therefore, it is necessary to connect the induction heating circuit after the voltage of the switching power supply is stable. You can connect an air switch between the power supply and the main board, and wait for the switching power supply. After the electricity is stable, push the air switch;

3. This circuit has very strict power requirements. The 12V power supply must use a power supply greater than 500W, 24V greater than 1200W, 36V greater than 2000W, 48V greater than 3000W (recommended operating voltage 48V);

4. No matter it is used at any voltage, as long as the working current is lower than 60A, the circuit will not burn out. The alarm current can be set to 60A through the maximum current setting of the power meter. heat dissipation.

5. The working voltage must not be lower than 12V;

6. When the heating machine is working, the heating ring will generate a high amount of heat, and water cooling must be used to cool the heating ring to avoid damage to the motherboard due to high temperature;

8. The power input port is marked with positive and negative, do not reverse it!

9. Do not power on with no load (here no load means that the output is not connected to any load, and the heating coil does not heat the object is not counted as no load), otherwise the board will make high-frequency noise, instantly burn the motherboard, and completely scrap it!

10. When using a graphite crucible, a non-circulating water-cooling method must be used, that is, the cold water enters the hot water and is discharged into the sewer to prevent the long-term high water temperature from affecting the service life (this water-cooling method should also be used for long-term high-power operation), The 12V auxiliary power supply must not be disconnected if the crucible is not taken out of the heating ring after heating, otherwise the water pump will stop working and the heating ring will be burned out by the temperature of the crucible

Four: how to use

1. Connect the wires according to the wiring diagram, check them carefully, and do not connect them by mistake.

2. Plug in the 12V2A power supply to AC110V-220V first, and observe whether the water pump and fan work normally.

3. If the water pump fan is working normally, plug in the DC48V power supply to AC220V, wait for about a few seconds and observe whether the voltage of the power meter on the motherboard is about 48V.

4. If the voltage display is normal, you can press "heating on" to turn on the heating, the green indicator light is on and the power meter has current, it means the heating is turned on.

5. If you want to turn off the heating, press the "Reset" button to turn off the heating, the green indicator light goes out, and the current of the power meter returns to zero.

6. This heating plate has overload protection and system water shortage protection. If the water pump does not work normally or there is water shortage in the water pump, the system will automatically protect and cut off the heating, and the red indicator light will be on.

7. The maximum current and minimum input voltage can be set to the maximum input voltage alarm. For detailed settings, see the attachment, the setting method of the power meter.

8. If the red light turns on and the heating stops during use, first check whether there is water flowing in the water pump. If the water cooling is normal, check whether the maximum current alarm is exceeded. The default maximum alarm current is 58A.
