Description:（This is an Assembled Product） This heating module uses a large PCB layout design which ensures a good heat dissipation and high power. There is a built-in cooling fan. It can work for DIY players and meet need for small parts quenching, annealing and other heat treatment. It can also be used with a graphite crucible to smelt gold, silver, copper, aluminum and other metals. Rapid and uniform heating is very convenient. The induction heating power supply is recommended to use more than 24V 10A switching power supply. The greater the voltage, the greater the current, the greater the heating power, the faster the heating rate. Features: Heating plate with large PCB design, component layout is sparse to heat dissipation. Power line design can increase the current heat radiation and makes the board smaller and more stable. Anti static 42*35 large heat sink ensures a good heat dissipation effect. The output end of the three pillars of parallel and 300V/25A terminals, two output modes, easy to use under different requirements. The positioning hole and the positioning hole of the heat radiating fan of the board and the 9*9cm are exactly matched with the positioning hole of the board, and the 12V power supply is directly inserted on the board. Specifications: Input Voltage: 12V-36V( recommended 24V) Power Requirements: less than 12V ≥5A more than 15V ≥10A Assembled Size: 90 * 180 * 65mm / 3.54 x 7.08 x 2.56" Package Includes: 1 x Assembled Heating Module
