Tesla Coil Heating Board Outdoor Crafts For Worker Feature:1. The induction heating circuit uses 12-48V DC low-voltage power supply, 1000W power, and the heating speed is fast.2. Used for heat treatment such as quenching and annealing of small parts, and can also be used with graphite crucible for metal smelting.3. Using excellent PCB manufacturing, the power cord is full copper, which greatly increases the current.4. Using 5 teeth 4 holes high power heat sink, which has better heat dissipation, safer to use.5. The output terminal uses M4 brackets in parallel, which can be connected to other outputs such as a high-voltage pack.6. There is a 2.54mm port on the board, after connecting the regulator, connect the cooling fan and water pump to use. Specification:Item Type: Heating PlateInput Voltage: 12-48V, 36V RecommendedPower Requirements: ge; 10a (less than 12V), ge; 15A (above 15V)Heating plate size: Approx. 100x100mm / 3.9 x 3.9inHeat sink size: Approx. 100x32x58mm / 3.9x1.3 x 2.3inPrecautions for use:1. The minimum input voltage of this module is 12V, but this does not mean that all 12V power supplies can be used. The voltage is 12V and the current must be above 10a before the power supply can be used. If the power of 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, two MOS transistors will be turned on at the same time. I burn out the MOS pipe.2. Some buyers will not notice that the power supply requirements cause the MOS pipe to heat up when using it. If you find that the MOS pipe is abnormally heated, first consider whether the power supply output meets the requirements.3. The plate should not be discharged, otherwise it will emit high-frequency noise, and then the MOS pipe will heat up and burn out.4. It is recommended to use a 36V20A power supply for induction heating. The 12V power supply is too low and there is almost no response to heating. Moreover, heating a 12V power supply will easily reduce the output voltage of the power supply and is very dangerous if it is lower than 12V.5. The induction heating power is very large and heat is inevitable, so be sure to do a good job of heat dissipation.6. Although this control board can withstand currents above 20A, to prevent accidents and damage, it is recommended not to exceed 48V 20A.7. The built-in heating ring has a diameter of 40mm and a rated voltage of 24V. If you are using a voltage above 30V, you need to use a heating ring with an inner diameter of 50mm or larger. Both the fan and the water pump use 12V DC power supplies. Please power them separately to avoid burning the fan and water pump.8. When doing induction heating, please use the copper pipe that is matched with this product, or wind it according to the standard of 8 circles with an inner diameter of 40mm, otherwise the buyer will be responsible for any combustion problems.
