Features Maximum power: ZVS low voltage induction heating board module uses low-voltage DC power supply 12-48V, maximum current 20A, maximum power 1000W, and 53V power supply during normal operation. 8.5mm thick custom substrate: Flyback driver heater uses an 8.5mm thick custom substrate to increase the heat sink, which has a very strong cooling capacity. The heating module adopts M4 column, which produces less heat and higher efficiency. Even and fast heating: ZVS induction heating board can use graphite crucible to melt gold, silver, copper, aluminum and other metals, heating evenly and quickly, which is very convenient Application: 1000w driver board, because of its moderate power, can be used for hardening, annealing and other heat treatments for small parts DIY players Note: For the same thing, the higher the voltage, the greater the heating current, the better the effect, but at the same time the heat generation is also large, so choose the input voltage according to the actual situation, generally 24V or 36V power supply is enough Features: This section of induction heating using low-voltage DC power supply 12-48V Maximum current 20A, maximum power 1000W. Tested 53V power supply when working properly. Because of its moderate power, can be used for small parts DIY players do hardening, annealing and other heat treatment, Also can be used with a graphite crucible melting gold, silver, copper, aluminum and other metals, uniform heating fast, very convenient. Specifications: Inside diameter of the coil: 40mm Height of the coil: 50mm 24V input with no load current of 3A 48V input with no load current of 6A It suits 12-36V power supply (not included) The coil accept 40mm crucible. Note: 1, The kit contains a full set of driving circuit elements and brass 2, Buyers need to bring their own power and cooling unit. 3, The circuit board using double-sided fiberglass board, mainly copper traces are used to widen use the entire back surface of the resonant circuit common, continuous work, please add a fan to blow down from above, to the resonance capacitors and other components cool. 4, The use of switching power supply Please note that due to high power are generally slow start function, which just opened machine output voltage is slowly rising, while it is turned on before the induction heating circuit if the voltage rises to 12V, because start insufficient voltage can not afford to vibration, resulting in two simultaneous conduction mos tube so burned components. So the first will start switching power supply voltage reaches 12V above and then access the induction heating circuit.
