Feature: 1. EASY TO MELT: Induction heater module is easy to melt metals such as iron, copper, gold, silver and aluminum with even heating and fast and very convenient. 2. DC12V-48V POWER SUPPLY: 2500W ZVS induction heater adopts DC12V?48V power supply, maximum current 50A, maximum power 2500W. 3. USE: Induction heater is used for heating and quenching small ferrous metal materials with 70mL graphite crucible up to 1600 degrees Celsius. 4. HEAT DISSIPATION: Heating PCB board module adopts large heat sink and large power supply to ensure better heat dissipation. 5. PCB MATERIAL: Induction heating machine module is made of PCB grade material, stable performance and not easy to damage. Specification: Item Type: 2500W ZVS Induction Heater Material: PCB Product Size: Approx. 120x240x85mm / 4.7x9.4x3.3in Maximum Power: 2500W Maximum Current: 50A Heating Circle Inner Diameter: Approx. 60mm/2.4in Heating Ring Height: Approx. 52mm/2.0in. Package List: 1 x 2500W ZVS Induction Heater1 x Power Adapter Plate1 x Copper Pipe1 x Water Pump1 x Water Pipe1 x Air Switch1 x 12V Power Supply1 x 48V Power Supply 3000W1 x Power Cord Note: 1. The heating ring will generate high heat when the heater is working, the heating ring must be cooled by water cooling to prevent damage to the motherboard due to high temperature.2. The power input is marked positive and negative, do not reverse.3. Heating ring may be deformed during transportation, after correction can be used normally.4. Do not idle power (here idle means that the output is not connected to any load, the heating ring does not heat the object is not idle).5. Please allow some error due to manual measurement.
