Product Overview: Enhance your Tesla coil experiments with our Multifunctional Fiber Optic Control Box, designed specifically for DRSSTC (Dual Resonant Solid State Tesla Coil) applications. This advanced controller offers reliable arc extinguishing, precise music control, and a convenient rechargeable design, making it an essential tool for Tesla coil enthusiasts and researchers. Key Features: Fiber Optic Signal Transmission: Utilizes optical fiber to transmit arc extinguishing signals, effectively avoiding interference from the strong electromagnetic fields generated by the Tesla coil. Square Wave Music Input: Supports square wave music input, allowing for seamless integration of musical effects with your Tesla coil. Built-In Rechargeable Lithium Battery: Eliminates the need for an external power supply during debugging, providing greater convenience and mobility. Pulse Width and Frequency Control: Features potentiometers for adjusting pulse width and frequency. Both controls increase with clockwise rotation and decrease with counterclockwise rotation. The pulse width control also has a built-in switch function. Automatic Burst Function: The second-generation controller includes an automatic burst function, enabling intermittent operation. The burst interval can be adjusted using the knob. Music Decoding Function: Integrated music decoding for TF cards, supporting MP3 and WAV formats. Includes an audition output interface for checking decoding via headphones. High Performance: Achieves a maximum frequency of 450Hz and a pulse width of up to 100us. Note that actual values may vary slightly due to component differences.
