Stark 40cm Height High Voltage Inductive Arc Musical Tesla Coil Experimental Physics ToyFeatures:.Design Original Intention: This large Tesla coil is small and easy to carry. It will not be dangerous if it is directly plugged into 220V. It does not need to be connected to the transformer. The demonstration effect is good and the power is controllable. Large integrated heat sink, extremely low heating rate, integrated feedback and insurance on the circuit board, safe and secure. Dual mode arc extinguishing, you can input square wave music, you can also manually control, you can manually adjust the frequency and pulse width..Features: Small size, high power; easy to use, arc extinguishing battery; multiple insurance, safety and stability; low heat, high stability..How to Use: First connect the product with a ground wire, connect one end to the screw at the end of the product, and connect the other end to a well-grounded metal (water pipe, fire pipe); connect the product and the arc extinguishing controller with an optical fiber cable, and turn on the arc extinguishing controller, Turn off the arc extinguishing after adjusting the pulse width to the minimum; connect the main body of the product with 24V and 220V power respectively; confirm that the discharge needle is installed correctly before use..Note: 1. The product is high voltage, please do not approach it during discharge; please turn off the arc extinguishing after use, and then move the product; the ground wire must be connected well. 2. Tesla Coils are potentially dangerous devices and precautions must be taken before every operation to help prevent possible damage to property, injury, or death. Unqualified persons should never be allowed to operate the Tesla Coil. Prior knowledge of high voltage electrical safety is required, and assumed. .Significance and Value: This product can be used for teaching demonstrations, explaining the knowledge of Tesla coils, or as a desktop technology ornament. It is more exhibitable. It is also suitable as a popular science educational toy gift for students and children. It is magical, fun and exciting Learning enthusiasm and interest in scientific exploration, cultivate innovation ability and creativity. .For Age: 12+Specifications:.Color: As Shown.Material: Metal + Acrylic + Electronic Components.Voltage: 220V.Power: 800W.Product Dimensions: 12 x 18 x 40cm.Product Weight: 2000g.Package Dimensions: 15 x 20 x 45cm.Package Weight: 3200g.Packing: BoxPackage Content:.1 x Large Tesla
