400KV High Voltage Pulse Generator Module

400KV High Voltage Pulse Generator is a compact module that converts low DC voltage (3.7V–6V) into a high-voltage DC pulse output. Widely used in DIY ignition projects, physics experiments, and high-voltage testing, this module can generate impressive arc discharges and demonstrate capacitor-based charge-discharge effects. It’s designed for momentary applications requiring extremely high voltage but low current output.
