Description
This high-voltage generator module is designed for scientific experimentation and small-scale production. It utilizes the Tesla coil principle and provides a powerful, high-voltage pulse current ideal for high-energy experiments.
400KV Generator Specifications
- Input Voltage: DC 3V to 6V
- Input Current: 2A – 5A
- Output Voltage: 400,000V (Handle with caution)
- High Voltage Discharge Distance: 10mm – 20mm
- Output Wire Length: 100mm
- Input Power Cord Length: 100mm (Red is positive)
Wiring: Connect the power with the red line as “+” and green as “-”.
Safety Notice:
- Avoid No-Load Usage: Power must be adjusted based on the high-voltage output line distance.
- Ensure the battery capacity matches the desired arc distance.
- Intermittent Use Only: Limit continuous operation to 1 minute to prevent module damage.
- Avoid short-circuiting the output.
- Arc Distance Testing: Begin with a shorter arc distance and gradually increase.

1000KV Generator Specifications
- Model: MC-901
- Input Voltage: DC 3.7V to 7.4V
- Input Current: 0.5A – 1A
- Output Voltage: 800KV – 1000KV
- Output Current: 0.5A – 1A
- High Voltage Discharge Distance: 15mm – 20mm
- Size: 88mm x 26mm
- Output Wire Length: 16cm
Usage Instructions:
- Connect the red and green input wires to a battery (red is positive).
- Avoid operating without a load on the high-voltage side to prevent module damage.
- Use a battery with a capacity above 2000mAh for optimal performance. High-capacity batteries (4000mAh+) are recommended.
Note on Power Supply: Compatible with a single 3.7V lithium battery or two in series (such as 18650). Lead-acid, NiCd, or NiMH battery packs (4V or 6V) are also suitable, with 6V providing optimal results.
Operating Precautions:
- No-Load Caution: Maintain an appropriate arc distance based on the power supply and battery capacity.
- Arc Distance Testing: Gradually increase distance, staying within the module’s capacity to avoid damage.
- Heat Management: Operate for short durations (within 10 seconds) to prevent overheating.
- Battery Check: Measure battery voltage while operating to ensure it maintains around 6V during high-power output.
Package Includes:
- 1 x High Voltage Generator Module (3V-6V to 400KV or 3.7V-7.4V to 1000KV)
