【Low Voltage Induction Heating Board Module】Also can be used with a graphite crucible melting gold, silver, copper, aluminum and other metals, uniform heating fast, very convenient. To increase the heat sink using a customized substrate as thick as 8.5mm! Cooling capacity is very powerful. Using the M4 pillars, fever smaller, more efficient. 【12-48V Low Voltage Power Supply】This section of induction heating using low-voltage DC power supply 12-48V. Tested 53V power supply when working properly. 【High Power High Efficiency】Low Voltage Induction Heating Power Supply Driver Board Module With Coil Maximum current 20A, maximum power 1000W. 【Fuction】Because of its moderate power, can be used for small parts DIY players do hardening, annealing and other heat treatment 【Note】Although this circuit can tolerate 20-30A input current moment, but do not exceed 15A when safe work, you can easily add an ammeter between the power supply and heating driver board but always monitor the current overload.
