Feature:1. The heating plate is made of grade PCB, it has stable performance.2. The power line is fully covered with copper cover, which can increase the current and heat generation.3. This product uses large and large power supply, ensures better heat dissipation effect.4. The output terminal uses three copper columns in parallel, which can be connected to other outputs such as high-voltage packet.5. Using 6 IRFP260s and 12 parallel resonant capacitors, high power, high efficiency.6. It can be used for DIY players to do quenching, annealing and other heat treatment for small parts. It can also be used with graphite crucible to smelt gold, silver, copper, aluminum and other metals. It can heat evenly and quickly, which is very convenient.Spec:Item Type: Induction HeaterPump Input Voltage: DC 12VInput Voltage: 12V-48V, recommended above 36VPower Requirement: ＜12V ≥10A, ＞15V ≥20AMaximum Power: 2500WMaximum Current: 50AUse: It can be used for DIY players to do quenching, annealing and other heat treatment for small parts.
