Features 53V power supply tested when working properly. This induction heating section uses 12-48V low voltage DC power supply It can also be used with a graphite crucible to melt gold, silver, copper, aluminum and other metals, fast uniform heating, very convenient. Due to its moderate power, it can be used for small parts that DIY players do hardening, annealing and other heat treatments. Maximum current 20A, maximum power 1000W. Specifications: Coil Inner Diameter: 40mm Coil height: 50 mm 24V input with 3A idling current 48V input with 6A idling current The higher the voltage, the higher the heating current when the same, the effect is better, But at the same time, the heat is also large, so to eradicate the actual situation to select the input voltage, the general use of the words 24V or 36V power supply is enough. Fits 12-36V power supply (not included) Coil accepts 40mm crucible. Note: 1, The kit contains a complete set of conduction circuit elements and brass 2, Buyers should bring their own power and cooling unit. 3, the circuit board uses double-sided fiberglass board, mainly copper traces are used to expand the use of the entire back surface of the common resonant circuit, continuous work, add a fan to blow from above, to the resonance capacitors and other cool components. 4, the use of switching power supply Please note that due to the high power, the start function is generally slow, which just opened the output voltage of the machine slowly increases, while turning on before the induction heating circuit if the voltage increases to 12V, because the start insufficient voltage cannot afford vibration, resulting in two simultaneous conduction MOS tubes, so the components are Burn. So the first will start switching the voltage of the power supply reaches 12V above and then access the induction heating circuit.
