Tesla coil arc extinguishing DRSSTC dedicated fiber optic controller multi-function finished music control box
The module uses optical fiber to transmit the arc extinguishing signal, which can effectively avoid the interference of the strong electromagnetic field generated by the Tesla coil on the signal. It adopts square wave music input and built-in lithium battery rechargeable design, allowing you to drag one less power supply during debugging. It is very convenient. The pulse width control potentiometer also has a switch function. It can be turned off when you hear a click sound by turning it counterclockwise. The pulse width and frequency control are both clockwise rotation to increase, and counterclockwise rotation to decrease.
Related technical parameters: the highest frequency is 450HZ, the pulse width is up to 55US [this parameter is the actual test value, due to the difference of the components, there may be some errors in practice]
The complete set of controller includes:
A 5m ST-ST multimode optical fiber cable,
One audio cable,
A finished controller
