Features 1、This is a non-tap mini ZVS finished board excluding heating coil, transformer, cooling fan, etc. 2、The maximum power is 120W (12V induction heating). Push the transformer 12V, the primary 5+5 turns, about 30W. 3、Input voltage DC 5V~12V, this voltage range is the voltage at work, not the voltage when the power supply is empty! (The voltage exceeds 12V or below 5V. We do not guarantee that it can work normally.) 4、Make sure that all components are soldered correctly, the positive and negative poles of the power cord are not reversely connected, after the load is connected (heating coil, transformer), and then power on! Can not power on at no load which makes it easily broken. 5、When inductive heating, usually work for 5 minutes to power off cooling. Because the current is relatively large during induction heating, the coil heat is also relatively large. When heating, part of the heat generated by the heated object is transmitted to the heating coil. For a long time, the temperature of the heating coil is high. If the heating coil is connected to the terminal, the plastic part of the terminal will be melted! Therefore, it is best to solder the heating coil directly to the PCB during induction heating. Please pay attention to this point. Specification Item Type:Induction Heating Board Maximum Power:120W(12V Inductive Heating) Package List 1 x Module 1 x Coil
