This induction heating section using low voltage DC power supply 12-48V 20A Max current, 1000W maximum power. Tested 53V power supply when working properly. Due to its moderate power, can be used for small parts DIY players do not quenching, annealing and other heat treatment, can also be Used with graphite crucible melt gold, silver, copper, aluminum and other metals, fast uniform heating, very convenient. Input 24V without current of 3A, 48V input without current of 6A The higher the voltage, the more the heating current when the same, the effect is better, but at the same time heat is as great, so as to eliminate the actual situation to select the input voltage, the general use of words 24V or 36V power supply is sufficient. (Package includes: 1 x ZVS Low Voltage Induction Heating Board, 1 x Brass)
