Features GREAT HEAT DISSIPATION --- This induction heating board adopts super large PCB layout design and heat sink, with silent fan, providing good heat dissipation. COPPER COLUMN OUTPUT --- The output end uses three M4 copper columns in parallel, which can be connected to other outputs such as high voltage packs. EXCELLENT COMPONENTS --- The induction heating module uses four IRFP260 and nine capacitors in parallel resonance, with high power and efficiency. HIGH POWER --- This induction heating circuit uses a 12 to 48V low voltage DC power supply, with a maximum current of 40A and a maximum power of 1800W. WIDE USAGE --- Can be used by DIY players to perform heat treatment such as quenching and annealing on small parts, and can also be paired with a graphite crucible to smelt metals, heating evenly and quickly.
