Dimensions: length, width and height 240*120*85 (unit: mm);</span></p><p><span style="font-size:18px">2. Input voltage: DC12-48V;</span></p><p><span style="font-size:18px">3. Maximum power: 2500W;</span></p><p><span style="font-size:18px">4. Maximum DC working current: 50A</span></p><p><span style="font-size:18px">5. The maximum temperature of direct heating of metal iron is 800-900 degrees Celsius</span></p><p><span style="font-size:18px">6. The maximum temperature of the crucible is 1600 degrees Celsius</span></p><p><br/></p><p><span style="font-size:18px"><strong>Matters needing attention (must read before use)</strong></span></p><p><span style="font-size:18px">1. The power of induction heating is very large. In addition to the heat generated by the PCB board and electronic components, the heating coil generates a large amount of heat. In order to avoid the heating coil from burning out and affecting the entire system, be sure to match the heating coil cooling water pump;</span></p><p><span style="font-size:18px">2. You must pay attention when using switching power supply, 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 voltage is turned on before the induction heating circuit rises to 11V, it will be affected by the voltage. The circuit can’t vibrate due to not enough, 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 switching power supply voltage is stable. You can connect an air switch between the power supply and the main board and wait for the switching power supply. Push the air switch after the electricity stabilizes;</span></p><p><span style="font-size:18px">3. This circuit has very strict requirements on the power supply. The 12V power supply must use a power supply greater than 500W, 24V greater than 1200W, 36V greater than 2000W, 48V greater than 2600W (recommended working voltage 48V);</span></p><p><span style="font-size:18px">4. No matter it is used under any voltage, as long as the working current is lower than 50A, the circuit will not be burnt out. Therefore, a 50A fuse can be added to protect the circuit during high-power operation;</span></p><p><span style="font-size:18px">5. It is inevitable to generate heat during high-power operation, so you should use a fan to top-blower to effectively dissipate heat while working;</span></p><p><span style="font-size:18px">6. The working voltage must not be lower than 12V;</span></p><p><span style="font-size:18px">7. 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 main board due to high temperature;</span></p><p><span style="font-size:18px">8. The power input terminals are marked with positive and negative poles, do not connect them in reverse!</span></p><p><span style="font-size:18px">9.The heating ring may be deformed during transportation, resulting in a short circuit between the layers. Please separate and then connect the main board, otherwise it may be overloaded and burn the main board.</span></p><p><span style="font-size:18px">10. Do not power on with no load (no load here means that the output is not connected to any load, and the heating coil is not connected to heat the object is not regarded as no load), otherwise the board will emit a high frequency noise, instantly burn the main board, and completely scrap!</span></p><p><br/></p><p><span style="font-size:18px"><strong>Precautions for use:</strong></span></p><p><span style="font-size:18px">1. The minimum input voltage of this module of 12V does not mean that all 12V power supplies can be used. Some novice buyers use power supplies with lower power. The specific voltage and current of this module have requirements. The voltage and current of 12V must be above 10A. If the power supply is too low, the actual output voltage of the power supply will be greatly reduced when the power is output. When the voltage is lower than 12V, it will cause the two MOS tubes to be turned on at the same time, which will burn the MOS tube;</span></p><p><span style="font-size:18px">2. Some buyers will not notice the power requirements of the power supply and cause the MOS tube to heat up when using it. If the MOS tube is found to be abnormally heated, first consider whether the output of the power supply meets the requirements.</span></p><p><span style="font-size:18px">3. The board should not be unloaded, otherwise it will emit high-frequency noise, and then the MOS tube will heat up and burn out</span></p><p><span style="font-size:18px">4. It is recommended to use 36V30A power supply for induction heating. If the 12V power supply is too small, there is almost no response to heating, and the heating of 12V power supply will easily cause the output voltage of the power supply to decrease. It is very dangerous if it is lower than 12V.</span></p><p><span style="font-size:18px">5. The induction heating power is very large, and heat is inevitable, so be sure to do a good job of heat dissipation.</span></p><p><br/></p><p><span style="font-size:18px"><strong>Product features and functions</strong></span></p><p><span style="font-size:18px">1.
