Specifications:Condition: Brand NewVoltage: DC12V-30VMax. Current: 20AMax. : 1000WSize: 69 x 85 x 30mm / 2.71 x 3.34 x 11.81 inchColour: BlackMaterial: Plastic+MetalThe driver module is made of high standard 1.6mm double layer fiberglass board for durability.Factory customized inductance coil is winded with 1.2mm copper wire for more stableperformance and 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 and current is more than 10A. The higher the voltage, the longer the arc (testedwith 27V/15A supply and it can generate 80mm long arc). As a induction heating board, thehigher the voltage, the faster and hotter heating will be. Recommended heating object diameter is less than 2/3 of coil.Package Contents:1pc x ZVS BoardOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
