1、GREAT HEAT DISSIPATION: This induction heating board adopts super large PCB layout design and heat sink, with silent fan, providing good heat dissipation. 2、COPPER COLUMN OUTPUT: The output end uses three M4 copper columns in parallel, which can be connected to other outputs such as high voltage packs. 3、EXCELLENT COMPONENTS: The induction heating module uses four IRFP260 and nine capacitors in parallel resonance, with high power and efficiency. 4、HIGH POWER: This induction heating circuit uses a 12 to 48V low voltage DC power supply, with a maximum current of 40A and a maximum power of 1800W. 5、WIDE USAGE: Can be used by DIY players to perform heat treatment such as quenching and annealing on small parts, and can also be paired with a graphite crucible to smelt metals, heating evenly and quickly. 1 x PCB Board1 x 5mm Copper Tube Item Type: Induction Heating BoardMaterial: PCB, brassInput Voltage: 12-48V, recommended above 36VPower Requirements: Less than 12V ≥10A, more than 15V ≥15ACapacitance: 9 x dedicated 1200V capacitorsFan: With a silent fanMoss Tube: 4 x IRF260Maximum Power: 1800WMaximum Current: 40ANote: 1. During induction heating, the power is very high. In addition to the PCB board and electronic components, the heating coil also generates a large amount of heat. To avoid burning the heating coil and affecting the entire system, it is necessary to provide a cooling water pump for the heating coil; 2. Attention must be paid when using the switching power supply. Because the high power switching power supply generally has a slow start function, that is, the output voltage rises slowly at the beginning. If the voltage is connected to the induction heating circuit before it rises to 11V, the circuit will not vibrate due to insufficient voltage, so that MOS tubes on both sides will be connected 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 motherboard, and wait for the power supply to stabilize before pushing the air switch; 3. This circuit has very strict requirements for power supply. A 12V power supply must use a power supply greater than 500W, 24V greater than 1000W, 36V greater than 1500W, 48V greater than 2000W (recommended working voltage 48V); 4. Regardless of the voltage used, as long as the working current remains below 40A, the circuit will not burn out. Therefore, a 40A fuse can be added to preserve the circuit during high power operation; 5. It is inevitable to generate heat during high power operation, so a fan should be used to effectively dissipate heat while working; 6. The working voltage must never be lower than 12V; 7. When the heating machine is working, the heating coil will generate high heat, and water cooling must be used to cool the heating coil to avoid damage to the motherboard due to high temperatures; 8. The power input terminal is marked with positive and negative poles, do not reverse connect, and absolutely prohibit the use of AC power!! 9. The heating coil may deform during transportation, causing a short circuit between layers. Please separate it before connecting the motherboard, otherwise overload may occur and the motherboard may be burned out; 10. Do not power on the board with no load (here, no load refers to the output not connected to any load, connecting the heating coil without heating the object is not considered no load), otherwise the board will emit high frequency noise, instantly burn out the motherboard, and be completely scrapped!
