Package Include:1 x 48V 50A 3000W Power Supply Kit1 x Air switch1 x 2500W PCB Heating Board1 x Crucible1 x Copper Coil1 x Pump&Pipe Introduction:1. This version is a 2500W ZVS heating module, using an oversized PCB layout design and an oversized heat sink for heat dissipation.2. Powerful, self-contained cooling fan interface, can also for Tesla discharge, mark generator, high voltage inverter power supply, etc.3. This product can work continuously for several hours under good heat dissipation conditions. Features:1. This induction heating circuit uses a 12-48V low-voltage DC power supply with a maximum current of 50A and a maximum power of 3000W. 2. Continuous operation under conditions of good heat dissipation. 3. Because of its moderate power, it can be used for DIY players to quench, annealing and other heat treatment of small parts. 4. It can also be used with graphite crucible to smelt gold, silver, copper, aluminum and other metals. The heating is even and fast, very convenient.5. The heating plate is made of 240*120mm military grade PCB, and the performance is stable;6. The power  lines is fully covered with copper cover design, which can increase the current and heat generation;7. It is better to use the extra large and large power heat sink to dissipate heat;8. The output terminal uses three M4 copper columns in parallel, which can be connected to other outputs such as high voltage package.9. Six IRFP260 and 12 capacitors are used for parallel resonance, which has high power efficiency; Specification:1. Name: Heating Board + Coil + Power supply + Pump2. Model: C105963. Material: Metal4. Input Voltage: 12V-48V (recommended 36V above)5. Power requirements: <12V(≥10A); 15V(≥10A);24V(≥20A)Note: The higher the voltage, the larger the current. The higher the heating power, the faster the heating rate.6. Maximum power: 2500W7. Maximum current: 50A8. Heater ring inner: 70mm (Recommended crucible + quartz suit, maximum support of 58mm crucible)9. Power Supply: 48V 50A 3000W Note:1. The power of heating is very large, except that the plate and components are hot, and the heat of copper tube is very high. The buyer can prepare water cooling system separately, can buy a small water pump and 2 meters of inner diameter of 4mm rubber hose.2. You must pay attention to when using switch power supply, because the high-power switching power supply usually have soft start function, namely the output voltage is slowly rising, and if the voltage rise to 10V before connected induction heating circuit will be caused by lacking voltage lead to circuit can't afford to vibrate, so that the two MOS tube conduction and burned components at the same time, so be sure to switch the power supply voltage stability and then access the induction heating circuit.3. When heating the metal objects do not to heat too large metal, otherwise it may be overloaded with power, please add a 45A fuse or ammeter and air switch will be better. (package does not inclues)4. Although this drive plate can withstand more than 50A current, but it is recommended that not exceed 48V 45A to prevent accidents and damage.5. Package comes with heating circle diameter is 60 mm, design voltage is 36V, if you use more than 40 voltage power supply shall be used for inner diameter 70 mm above diameter heating ring, water pump use 12V dc power supply, please use separate power supply voltage regulator module to avoid burn out fan and water pump.6. The minimum input voltage of the module is 12V, it doesn't mean all the 12V power supply can be used, some novice buyers may use a smaller power supply. This module has specific voltage and current requirements, the voltage 12V current must be more than 10A power supply can be used, if the power is too low will lead to the power output is greatly reduced, when the voltage is lower than 12V, it will lead to two MOS at the same time conduction, will burn MOS tube;7. If you find that the MOS tube fever, then the first thing to consider whether the power output meets the requirements.8. Do not empty the board, otherwise it will issue a very high frequency of noise, and then MOS tube will burn out9. Induction heating is recommended to use 36V 20A power supply, 12V power supply is too small heating almost no response, and 12V power supply easily lead to the power supply output voltage decreases, below 12V is very dangerous10. Induction heating power is great, so getting fever is normal, be sure to do a good job of cooling.11. Induction heating, the power recommended more than 48V 50A switching power supply. More than 24V power supply, then more than 20A power supply, the greater the voltage, the greater the current, the greater the heating power, heating faster.
