Features: 1.Parameters: This induction heating circuit uses 12?48V low voltage DC power supply, the maximum current is 50A, the maximum power is 2000W. 2.Uniform and Fast Heating: Heating uniform and fast, very convenient, under good heat dissipation conditions can work for several hours. 3.Uses: Used for small parts for quenching, annealing and other heat treatment, but also with graphite crucible melting gold, silver, copper, aluminum and other metals. 4.Stable Performance: The power line is covered with copper, which can increase the current and generate less heat, and the performance is stable. 5.Excellent Heat Dissipation: The induction heating module adopts super large power heat sink and has excellent heat dissipation. specification:Item Type: Induction Heating Module Material: Aluminum Alloy, Brass Cooling Fan Size: Approx. 120 x 240mm / 4.7 x 9.4in (error in Manual Measurement) Input Voltage: 12-48v, Above 36v is Recommended Power Supply Requirements: Less Than 12v 10A, More Than 15v 20A Maximum Power: 2000w Maximum Current: 50A 1. The power of induction heating is very large. In addition to the heating of boards and components, the calorific value of copper tubes is also very large. Buyers can prepare their own water cooling system, you can buy a small water pump and about 2 meters of inner diameter of 4mm rubber water pipe; You can also buy the water pump in the package. 2. We must pay attention to the use of switching power supply, because the high?power switching power supply generally has a slow start function, that is, the output voltage at the beginning of the slow rise, and if the voltage rises to 10V before the induction heating circuit will be connected because the voltage is not enough to cause the circuit vibration, so that the two for MOS tube at the same time on and burn components, So be sure to access the induction heating circuit after the switching power supply voltage is stable; 3. When heating metal objects, try not to heat metal with too large volume, otherwise it may be dangerous due to overload of power; Use the best to add a 50A fuse or ammeter and air switch is better, can be optional in the package. 4. Although the drive board can withstand more than 50A current, in order to prevent accidents and damage, it is recommended not to exceed 48V 55A for a long time continuous work. 5. The diameter of the heating ring delivered with the package is 60mm and the designed voltage is 86V. If the power supply is greater than 40V, the heating ring with an inner diameter greater than 60mm must be used. 6. For induction heating, the copper pipe in the package of this product should be used, or it should be wound according to the standard of 10 rings with an inner diameter of 60mm. Otherwise, the buyer shall bear the responsibility for any burning problem. PackageList:1 x Induction Heating Module 1 x BrassCoil Note1. The minimum input voltage of this module is 12V, which does not mean that all 12V power supplies can be used. Some novice buyers use the power supply with smaller power. The power of the power supply is too low, which will cause the actual output voltage of the power supply to be greatly reduced in the high power output. When the voltage is lower than 12V, two for MOS tubes will switch on at the same time, which will burn the for MOS tube. 2. Some buyers will not notice the power requirements of the power supply when using the for MOS tube heating, if the for MOS tube heating anomaly is found, we should first consider whether the output of the power supply meets the requirements 3. The board should not be empty, otherwise it will emit high frequency noise, and then the for MOS tube will heat and burn out 4. It is recommended to use a 36V 30A power supply for induction heating. The 12V power supply is too small to respond to heating, and the 12V power supply heating is easy to reduce the output voltage of the power supply, which is dangerous if it is lower than 12V 5. induction heating power is very large, heat is inevitable, must do a good job of heat dissipation.
