The newly designed ZVS induction heating product has a maximum power of 2000W, adopts an oversized PCB layout design and an extra large heat sink. It has good heat dissipation and high power, and has a cooling fan interface. It can also be used for Tesla discharge, Marx generator, high voltage inverse. Variable 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. Continuous operation under conditions of good heat dissipation. Because of its moderate power, it can be used for DIY play.
For quenching, annealing and other heat treatment of small parts, it can also be combined with graphite crucible to smelt gold, silver, copper, aluminum and other metals. The heating is even and fast, which is very convenient.
In this test, the maximum power is close to 2000W and the maximum current is 50A. This product is in it can work continuously for several hours under good heat dissipation conditions.
Product parameters:
Product size: 120mm * 240mm
Input voltage: 12V-48 recommended above 36V
Power requirements: less than 12V ≥ 10A 15V or more ≥ 20A
Maximum power: 2000W
Maximum current: 50A
For induction heating, it is recommended to use a switching power supply of 48V50A or higher. The higher the voltage, the larger the current, the higher the heating power, and the faster the heating speed.
[1] The power of induction heating is very large. 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-cooling cooling system, you can buy a small water pump and a rubber hose with an inner diameter of 4mm or about 2m; you can also purchase the matching water pump in the package.
[2] It must be noted when using a switching power supply, because a 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 If the voltage is not enough, the circuit will not vibrate, so that the two MOS tubes are turned on at the same time to burn the components. Therefore, it is necessary to connect the induction heating circuit after the switching power supply voltage is stable;
[3] 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 ammeter and air switch when using.
[4] Although this driver board can withstand more than 50A current, it is recommended not to exceed 48V55A in order to prevent accidents and damage for long-term continuous operation.
[5] The heating coil with the diameter of the package is 60mm, 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.
