Description: The newest designed ZVS induction heating product has a maximum power of 1800W. It adopts an oversized PCB layout design and an extra large heat sink. It has good heat dissipation and self-contained cooling fan interface. It can also be used for Tesla discharge, Marx generator, high voltage inverter. Power supply, etc. This induction heating circuit uses a 12-48V low-voltage DC power supply with a maximum current of 50A and a maximum power of 2000W for continuous operation under conditions of good heat dissipation. Because of its moderate power, it can be used for DIY players to do quenching, annealing and other heat treatment for small parts. 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. In this test, the maximum power is close to 2000W and the maximum current is 50A. This product can work continuously for several hours under the condition of good heat dissipation. Specification: PCB size: 180 * 90 * 80mm, Coil Dia.: 70mm Input voltage: 12V-48 recommended above 36V Power requirements: less than 12V ≥ 10A, 15V or more ≥ 20A Maximum power: 1800W Maximum current: 50A For induction heating, the power supply is recommended to use 48V 50A or more switching power supply. If the power supply is 24V or more, the power supply must be 20A or more. The higher the voltage, the larger the current, the higher the heating power, the faster the heating speed. Feature: The heating plate is made of 240*120mm military grade PCB, and the performance is stable. Power line full copper overlay design, can increase current and heat Uses extra large and large power heat sink to dissipate heat better The output uses three M4 copper columns in parallel, which can be connected to other outputs such as high voltage packages. Six IRFP260 and 12 capacitors are used in parallel resonance for high power efficiency note Inductive heating work is very powerful. In addition to the heat generated by the board and components, the heat generated by the copper tube is also very large. Buyers can bring their own water-cooled cooling system. You can buy a small water pump and a rubber hose with an inner diameter of 4mm or 2mm. You can also purchase a matching water pump. It must be noted when using switching power supply, because high-power switching power supply generally has a slow-start function, that is, it slowly rises when the output voltage starts, and if the voltage rises to 10V, the induction heating circuit is turned on because the voltage is not enough. The circuit does not vibrate, so that the two MOS tubes are turned on at the same time to burn the components, so it is necessary to connect the induction heating circuit after the switching power supply voltage is stable. When heating metal objects, try not to heat the metal with too much volume. Otherwise, the overload may occur due to power overload. It is better to add a 50A fuse or an ammeter and air switch when using. Although this driver board can withstand more than 50A, it is recommended not to exceed 48V 55A in order to prevent accidents and damage. The heating ring of the package is 60mm in diameter and the design voltage is 86V. If using 40V or more voltage supply, use a heating coil with an inner diameter of 60mm or more. The pump uses 12V DC power supply. Please use the voltage regulator module to supply power separately to avoid burning the fan and water pump.  For induction heating, the copper tube in the package of this product should be used, or it should be wound according to the standard of 10 mm inner diameter of 60mm. Otherwise, the buyer will bear the responsibility for any burning problem. This heating module is designed to be used in environments above 1800W. Precautions: According to the various questions from the small partners and the problems in use, please explain here, you must follow before using. 1. The minimum input voltage of this module is 12V. It does not mean that all 12V power supplies can be used. Some novice buyers use a power supply with a lower power. The specific voltage and current of this module are required. The voltage of 12V must be above 10A. 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, the two MOS transistors will be turned on at the same time, and the MOS tube will be burnt out. 2. Some buyers will not notice the power requirement of the power supply and cause the MOS tube to heat up. If it is found that the MOS tube is abnormally heated, first consider whether the output of the power supply meets the requirements. 3. The board should not be unloaded, otherwise it will emit high frequency noise, then the MOS tube will burn out. 4. Induction heating is recommended to use 36V 30A power supply, 12V power supply is too small, heating is almost no reaction, and 12V power supply heating is easy to cause the power supply output voltage to drop, it is dangerous to be lower than 12V. 5. The induction heating power is very high, and it is inevitable that heat is generated. It is necessary to dissipate heat.
