Features: The module uses the principle of a coil to output high-voltage pulses with intense discharge intensity. Supports pulsed DC high voltage with an input voltage range of 3.6V-7.4V and an output voltage of approximately 60KV. Universal ignition coil module with compact size and high efficiency; input does not require polarity distinction. Can be used as a high-voltage source for science experiments, electronic instruments, negative ion generators, and eonal projects. Suitable for high-voltage applications, electronic DIY, and product development.
