Feature: 1. FINE DESIGN: Induction heating board adopts a super large PCB layout design and a super large heat sink, which has good heat dissipation and high power. Comes with a cooling fan interface and can also be used for discharge, generator, high voltage inverter power supply, etc. 2. POWERFUL FUNCTION: The output end uses three M4 brass columns in parallel, which can be connected to other outputs such as high voltage packages; Using 6 IRFP260 and 12 parallel resonant capacitors, the heating board has high power and efficiency. 3. WORK DETAILS: This induction heating circuit uses a 12‑48V low voltage DC power supply, with a maximum current of 50A and a maximum power of 2500W. 4. WIDELY APPLICABLE: Induction heater can work continuously under good heat dissipation conditions. Due to its moderate power, the module can be used by DIY players to perform heat treatment such as quenching and annealing on small parts. It can also be paired with a graphite crucible(without) to melt metals such as gold, silver, copper, aluminum, etc., heating evenly and quickly, making it very convenient. 5. EASY TO INSTALL: Compact size make the module easy to install on the equipment and machine, ideal replacement for the old and damaged parts. Specification: Item Type: Induction Heater Material: PCB, Brass Input Voltage: 12V-48V, recommended above 36V Power Requirements: Below 12V, greater than or equal to 10A Above 15V, greater than or equal to 20A Fan: With a silent fan Maximum Power: 2500W Maximum Current: 50A 1. The heating power is very high, except for the boards and components being very hot, the heating capacity of brass pipes is very high. Buyers can prepare a separate water cooling system by purchasing a small water pump and a 2 meter rubber hose with an inner diameter of 4mm. 2. When using switching power supplies, attention must be paid because high power switching power supplies generally have a soft start function, and the output voltage rises slowly. If the Y voltage rises to 10V before, the circuit cannot withstand vibration due to insufficient voltage, causing two MOS transistors to conduct simultaneously and burn out components. Therefore, it is necessary to change the power supply voltage to stabilize, and then connect it to the heating circuit through induction. 3. When heating metal objects, please do not heat too much metal, otherwise it may cause power overload. Please add a 35A fuse or ammeter, and the air switch will be better. (Packaging not included) 4. Although this drive board can withstand a current of over 40A, it is recommended not to exceed 48V 35A to avoid accidents and damage. 5. The packaging comes with a heating ring with a diameter of 60mm and a design voltage of 36V. If a power supply with a voltage of 40 or higher is used, it is used for heating with an inner diameter of 70mm above the diameter of the heating ring The water pump adopts a 12V DC power supply. Please use a separate power regulator module to burn down the fan and water pump. 6. The minimum input voltage of the module is 12V, which does not mean that the entire 12V power supply can be used. Some novice buyers may use smaller power supplies. This module has specific voltage and current requirements, and the current 12V voltage must be greater than 10A. If the battery level is too low, you can use the power supply. This greatly reduces the output power. When the voltage is lower than 12V, it will cause both MOSs to conduct simultaneously and burn out the MOS transistor. 7. If encountering MOS tube heating, the first thing to consider is whether the output power meets the requirements. 8. Do not empty the board, otherwise it will emit high noise frequency and burn out the MOS transistor. 9. It is recommended to use a 36V 20A power supply for induction heating. The 12V power supply is too small and almost unresponsive, and the 12V power supply can easily cause a decrease in the output voltage of the power supply. It is very dangerous to use a voltage lower than 12V. 10. The induction heating power is excellent, so heating is a normal phenomena, and it is necessary to do a good job in heat dissipation. Induction heating, recommended power supply is a 48V 50A or higher switching power supply. If the power supply is above 24V, the power supply is above 20A. The higher the voltage, the greater the current, the greater the heating power, and the faster the heating.. Package List: 1 x Induction Heater1 x Brass Ring Note: 1. The minimum input voltage of this module is 12V, which does not mean that all 12V power supplies can be used. Some novice buyers have used low power power supplies, and there are specific requirements for the voltage and current of this module. Only power supplies with a voltage of 12V and a current of 10A or above can be used. If the po
