400KV High Voltage Pulse Generator Module – DC 3V-6V Step-Up Super Arc Inverter Coil for Science Projects

Overview

The 400KV High Voltage Generator is a miniature step-up transformer inverter module capable of creating impressive high-voltage electric sparks. By feeding a simple 3.7 V or 6 V battery supply into the input wires, the internal circuit converts the DC current into high-frequency pulses, firing a loud, visual electric arc across the output terminal wires. It is widely used by engineering and science students for electrostatic experiments, negative ion generators, and scientific instruments.

Key Features

• Incredible Step-Up Ratio: Transforms low-voltage battery power into a high-tension electrical discharge.

• Thick Protective Casing: The internal components are completely potted in a rugged, shock-resistant cylindrical resin shell to prevent internal arcing.

• Vivid Electric Arcs: Capable of producing continuous high-frequency sparks/arcs when the output distance is set correctly.

• Simple Wiring Layout: Color-coded input and output wires make it straightforward to integrate into battery-powered circuits.

Critical Operating Rules 

To prevent burning out this module within seconds, please follow these strict precautions:

1. Never Power Without Output Spacing: Before switching the unit on, fix the two thick output red wires at a distance of 1cm to 1.5cm apart. If you power the module while the output wires are too far apart, the energy will reflect backward and melt the internal coil insulation.

2. Short Duty Cycle Only: This module does not have an active cooling system. Run it for a maximum of 5 seconds per burst, and let it cool down between triggers.

3. Safety Warning: The output arc is extremely painful and dangerous. Keep well away from skin, pets, and flammable materials. Do not use this product as a weapon or for illegal devices.
