Induction heating is the process of heating an electrically conductive object (usually a metal) by electromagnetic induction, this is done through the internal generation of heat within the object via the use of Eddy Currents (also called Foucault's currents).
This 1000W Induction heater is a great introduction to small-scale induction heating projects. Since it's not high-powered, it can be used for small DIY parts for hardening, annealing and other heat treatments. When pairing this up with a graphite or porcelain crucible, It can be used to melt metals such as gold, silver, copper, or aluminum. The heating process is really quick and super convenient. Generally, the higher the voltage you use, the higher the current and better the heating results will be. (MAX. 48V / 1000W)

This unit does not come with any power supplies or cooling units. It is highly recommended that a cooling fan is used against the mainboard oscillators and ends of the copper coil. - If possible, we recommend running coolant through the copper tubing to increase cooling, this will, in turn, increase the heating effectiveness
If you are using a switch-mode power supply. Please make sure that the power supply is on at full 24V/36V before connecting it to the heater. Switch-mode power supplies can have a slow start-up period whereby the output is not immediately at full voltage. As the voltage ramps up, the induction heater can often turn on at a lower voltage than it should and engages the oscillators out of sequence. Therefore when the voltage is full, the oscillators are not firing correctly will cause the board to burn or not operate properly. Always wait for the power supply to reach its full voltage before connecting the induction heater.
The volume of the object being heated inside the heating coil should not exceed 1/5 of the volume of the heating coil, this may cause an overload on the induction heater board.
Although this circuit can tolerate 20-30A input current, It is safer to stick to a max of 15A. It is recommended to monitor your current with an ammeter.
There are 4 x M4 Metal Stand Offs for Fan Mounts.
