Features: This section of induction heating with low voltage 12-48V DC power supply Maximum current 20A, maximum power 1000W. Proven 53V power supply with proper operation. Due to its moderate power, it can be used do small parts by DIY do hardening, annealing and other heat treatment, It can also be used with graphite crucible melting gold, silver, copper, aluminum and other metals, even heating fast, very convenient. Technical data: Inner diameter of coil: 40mm Coil Height: 50mm 24V input without load current 3A 48V input without load current 6A The higher the voltage, the greater the heating current, when the same, the effect is better, But at the same time, the heat is also large, so to eliminate the actual situation, to choose the input voltage, it is enough to use the words 24V or 36V power supply in general. The coil accepts a 40 mm crucible. 1, set includes full set of drive circuit and brass components 3, printed circuit board using double-sided fiberglass board, mainly copper traces are used do widen the entire rear surface of the common resonance circuit, continuous operation, please add wentylator to blow from above, do resonant capacitors and other cool elements. 4, using switching power supply Please note,that due to the high power, the slow start function is generally slow,when the output voltage of the machine after opening slowly increases,while it is switched on before the induction heating circuit,if the voltage rises do 12 V,because insufficient tension cannot afford to vibrate,which causes two mos pipes to be conducted simultaneously, so the components burned. So the first one starts switching the supply voltage reaches 12V above, and then accesses the do induction heating circuit. 5, The volume of the heated object inside the heating coil must not exceed 1/5 of the volume (if the heating cylinder, then the diameter of the heating coil is less than 1/3 diameter), or it may be due to overload or burn out the circuit power supply. Although this circuit can tolerate an input current of 20-30A, but does not exceed 15A during safe operation, you can easily add an ammeter between the power supply and the heating controller board, but always monitor the current overload. This circuit can not only inductively heat, copper pipe do high frequency transformer, it is a powerful inverter. 1, To increase the radiator with a custom substrate up to 8,5 mm thick! The cooling capacity is very powerful. 2, using M4 pillars, fever smaller, more efficient. Package Included: 1 x ZVS Low Voltage Induction Heating Plate 1 x Brass
