Key Features Premium Materials: It is made of premium aluminum, PCB, and copper materials with a welding process, which is sturdy, reliable, not easy to deform, wear-resistant, impact-resistant. High-efficiency Heating: It utilizes electromagnetic induction technology and has a strong power of 1800W, which can quickly raise the temperature of the material and greatly improve the working efficiency. Good Heat Dissipation: It adopts a highly efficient heat dissipation aluminum heat sink, dual-fan design, and superb PCB layout to ensure efficient air circulation, quickly remove heat generated during the working process, and keep a stable temperature during long-time operation. Good Performance: It utilizes ZVS ( zero-voltage switching ) technology to provide more efficient energy conversion and reduce energy consumption. Application It can be used for DIY players to do quenching, annealing, and other heat treatments for small parts. It can also be used with a graphite crucible to smelt gold, silver, copper, aluminum, and other metals. It is also used for discharge, generator voltage inverter, etc. Specifications Material: Aluminum, PCB, Copper Process: Welding Style: Modern Color: Black, Gold Shape: Rectangular Assembly Required: Yes Power Requirements: Recommended Power Supply Below 40A, Optional 48V, 3000W Input Voltage: Recommended 12V-48V Maximum Current: 40A Maximum Power: 1800W Heating Ring Inner Circle: 70mm/2.76in (Recommended Crucible + Quartz Sleeve, Supports Up To 58mm/2.28in Crucible) Product Size: 18*9*8cm/7.09*3.54*3.1in Package Size: 30*13.5*12cm/11.81*5.31*4.72in Gross Weight: 1.2kg/2.65 lbs Net Weight: 1.14kg/2.51 lbs Package Included 1* Induction Heating Board Module 1* 48V Spiral Copper Tube Notes 1. This unit requires electronic knowledge and ability, please make sure you know how to use it. 2. Please note that the product generates a lot of heat. In addition to the pole plate and components generating a lot of heat, the heat generated by the copper tube is also very large. You need to prepare the water-cooling mechanism separately by purchasing a small water pump and a 6.56ft rubber tube with a diameter of 0.16". 3. Please note that you should be careful when using a switching power supply because high-power switching power supplies usually have a soft-start function, i.e., the output voltage rises slowly. If the voltage rises to 10V before connecting to the induction heating circuit, the circuit will not vibrate due to insufficient voltage, which will make the two MOS tubes conduct at the same time and burn out the components, so you must adjust the voltage of the switching power supply to stabilize before connecting to the induction heating circuit. 4. Please note that when heating metal objects, do not heat the metal directly. Otherwise, the power supply may be overloaded. Please add a 35A fuse or ammeter (not included) for better air switching. 5. Although this driver board can withstand 40A current, it is recommended not to exceed 48V 35A to avoid accidents. 6. The minimum input voltage of this module is 12V, which does not mean that all 12V power supplies can be used. Moreover, a 12V power supply can easily cause the output voltage of the power supply to drop, which is very dangerous to use. It is recommended to use a 36V 20A power supply for induction heating.
