Features Great Heat Dissipation: This Induction Heating Board Adopts Super Large Pcb Layout Design And Heat Sink, with Silent Fan, Providing Good Heat Dissipation. 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. Excellent Components: The Induction Heating Module Uses Four Irfp260 And Nine Capacitors in Parallel Resonance, with High Power And Efficiency. 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. Quenching And Annealing on Small Parts, And Can Also Be Paired with A Graphite Crucible to Smelt Metals, Heating Evenly And Quickly Wide Usage: CHigh 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. Specification: Item Type: Induction Heating Board Material: PCB, brass Input Voltage: 12-48V, recommended above 36V Power Requirements: Less than 12V ≥10A, more than 15V ≥15A Capacitance: 9 x dedicated 1200V capacitors Fan: With a silent fan Moss Tube: 4 x IRF260 Maximum Power: 1800W Maximum Current: 40A Note: 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.  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); Package List: 1 x PCB Board 1 x 5mm Copper Tube Package List 1 x PCB Board 1 x 5mm Copper Tube
