Size: 69 x 85 x 30mm / 2.71 x 3.34 x 11.81 inch Colour: Black Material: Plastic+Metal The driver module is made of high standard 1.6mm double layer fiberglass board for durability. Factory customized large inductance coil is winded with 1.2mm copper wire for more stable performance and consistent parameter. This ZVS driver module uses 5-band resistors for small error and stable performance. More tin is added on the board bottom so the driver board can be used for induction heating without burning out. Use 12-30V DC power and current is more than 10A. The higher the voltage, the longer the arc (tested with 27V/15A power supply and it can generate 80mm long arc). As a induction heating board, the higher the voltage, the faster and heating will be. Recommended heating object diameter is less than 2/3 of coil.
