Specifications: Name: Music Tesla Coil Type: White Base & Gold Coil/White Base & Blue Coil/Gold Base & Gold Coil/Blue Base & Blue Coil/White Base & Gold Coil & With Shell/White Base & Blue Coil & With Shell/Gold Base & Gold Coil & With Shell/Blue Base & Blue Coil & With Shell(optional) Plug: EU Shell Material: Acrylic Input: 100-240V Output: 24V,3A Item Size: -With Shell: 95 * 95 * 185mm -No Shell: 85 * 85 * 185mm Notes: 1.After welding, use a multimeter to check whether the input power supply is short-circuit, and then power on after confirming that there is no problem with welding. This product is safe, the power is not high, and it will not be injured by electric shock, but it is not recommended to touch the arc on the top of the coil, which will cause a burning feeling. 2. Do not touch the heat sink after a long time of power on. The temperature is very high, especially when the high voltage of 24V is used. If necessary, please add a cooling fan to dissipate heat, or if the working time is too long, it is too hot. Please turn off the heat sink for a period of time. 3. It is recommended that the body or other objects should not be close to the coil when the Tesla coil is working, that is, leave a space within half a meter beside the coil and no other objects, because other objects as a good conductor will make the coil form a good loop and absorb the coil energy, making the performance effect of the Tesla coil worse or unable to be demonstrated at this time! 4. Do not put the mobile phone, MP3 and other electronic devices close to the coil, otherwise the coil will produce high-frequency magnetic field interference, making the mobile phone, MP3 and other devices failure or even damage!
