DC 24-36V 20A induction heating board Flyback driver heater + ignition coil

Description:

The power line is fully covered with copper cover design, which can increase the current and heat generation.
23A overcurrent protection circuit has been added, to improve the safety performance of 90%, is not afraid to use battery-powered overcurrent bombing.
Uses: DIY small parts made of steel hardening, annealing below the melting point of 1100 ℃ metal smelting, DIY small cooker and so on.
Notice : Only direct heating a steel material ( the magnet can be adsorbed material) Gold, silver, copper, aluminum can not be directly heated, need to match the graphite crucible melting.
Found with a 36V power supply completely into the new 30 x 30 graphite crucible input current of 25A.
Found molten aluminum Power Requirements: 24V 350W - 500W power supply (15A to 20A) [melting point: 660 ℃].
Found melting copper, gold, silver, power requirements: 36V 700W - 900W power supply (20A to 25A), respectively [melting point: 1083 ℃, 1065 ℃, 962 ℃].

Note:

Work brass heating will need to use a lot of water circulation cooling,Without water circulating cooling are possible, but will burn into a black brass, it will not be much affected.
Note that the positive and negative input, large power reverse will burn components.
