ZVS 12-48V 20A 1000W Low Voltage Induction Heating Board High Frequency Induction Heating Machine Module

ZVS 12-48V 20A 1000W Low Voltage Induction Heating Board High Frequency Induction Heating Machine Module

• 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.
• The kit contains a full set of driving circuit elements and brass.
• 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.
• 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.
• The volume of the object being heated inside the heating coil can not exceed 1/5 of the volume(if the heating cylinder, then heating coil diameter less than the diameter of 1/3),or it may be due to overload or burn out the power supply to the circuit.although this circuit can tolerate 20-30A input current moment, but do not exceed 15A when safe work.
