Principle Introduction:

Tesla coil is a transformer that operates on the resonance principle. It was invented by Nicola Tesla, a Serbia-American scientist in 1891. It is mainly used to produce ultra-high voltage, but low current, high-frequency AC power. The Tesla coil is composed of two groups of resonant circuits (sometimes three groups) coupled.

The Tesla coil is difficult to define, and Nicola Tesla has tried a large number of configurations of various coils. Tesla uses these coils to carry out innovative experiments, such as electrical lighting, fluorescence spectrum, X-ray, high frequency alternating current phenomenon, electrotherapy, and radio energy transmission, transmitting and receiving radio signals.

Tesla function:

1. Electric arc function: the traverse of the rear end will produce an arc. The arc can also ignite.

2. Septum light function: after the Tesla coil is electric, the fluorescent lamp can be lit apart.

3. Music playback function: a new concept loudspeaker for an electric arc to stimulate air to make air vibration produced by plasma. You can play mobile/computer music, but the sound is small.

Installation steps:

1. Install small components at first;

2. Install complex components preferentially;

3. Pay attention to the installation direction of components.

4. Make sure the soldering iron does not touch the components for a long time. Otherwise, it is easy to damage the components.


1. This product is safe, the power is not high, will not be injured by electric shock, but it is not recommended to touch the top of the coil arc as there will be a sense of burning.

2. Do not touch the heat sink after a long time power supply, the temperature is very high, especially the use of 24V high voltage heat, if necessary, add their own cooling fan cooling, or if working hours lead to too hot, please turn off for a period of time Electric use.

3. Tesla coil is recommended to work when the body or other objects are close to the coil, the coil next to half a meter blank can not be other objects, as other objects as a good conductor will make the coil form a good loop, absorbing the coil energy, making Testers Pull the coil at this time the effect of demonstration or deterioration can not be demonstrated!

4. Do not put cell phones, MP3s, and other electronic equipment close to the coil, or the coil will produce high-frequency magnetic field interference, causing mobile phones, MP3s, and other equipment failure or damage!
