The Tesla coil power supply is only 32v DC, and the low-voltage power supply ensures safety, and the effect is stronger than most desktop-grade commercial half-bridge Tesla coils on the market. At low frequencies, you can freely play the arc between your palms. The frequency of the music mode is higher.
When the arc is concentrated at one point, there will be a burning sensation. The power supply is a DC power adapter, which does not need to be grounded, and is more stable. The heat sink is equipped with a temperature control switch.
The power supply has over-current protection. The pulse width of the music mode is limited and multiple protections are provided. The left knob controls the fixed frequency frequency, and clockwise speeds up the arc spray frequency.
It is best not to open the maximum arc in music mode all the time, so as to avoid the temperature control protection is too fast. If the arc in the music mode is turned to the maximum and sometimes discontinuous, this is caused by excessive power supply protection.
