The 400 kV Step Up Power Module is a compact high-voltage DC generator designed to boost a low DC input into a very high-voltage output. Commonly used in educational demonstrations, science experiments, ionizers, ozone generators, and ignition applications, this module produces visible sparks and high electric potential at very low current. Due to its size and simplicity, it is widely used in DIY high-voltage projects and electronics experimentation.
