AEDIKO 2pcs 3V-6V to 400kV High Voltage Generator
Brand: AEDIKO. This dual-pack module accepts a low DC input and delivers a high-voltage pulse suitable for demonstrations and experimental setups. Input range and safety considerations are essential given the extreme output potential. Typical applications include spark-gap experiments and educational demonstrations. Pay attention to safe discharge distances and insulation during operation.
AEDIKO 2pcs High Voltage Generator 6-12V to 1000kV
Brand: AEDIKO. This set expands the input range to 6–12 V with outputs reaching up to 1,000 kV. It emphasizes high-voltage pulse generation and efficiency through a Tesla-coil-inspired design. Suitable for advanced arcing experiments and controlled demonstrations with proper safety protocols.
DEVMO 5Pcs DC 3v-6v to 400kV High-Voltage Module
Brand: DEVMO. A five-pack offering for multiple experiments or parallel testing. Output voltage reaches about 400,000 V with a similar low-voltage input range. The modules rely on high-pressure pulse output and straightforward wiring, but require careful handling and proper insulation for safe operation.
JESSINIE 2PCs Booster Module (DC3.7V to 1800V)
Brand: JESSINIE. A compact boost module that delivers around 1.5–2 kV from a 3–4.2 V input, using a voltage-doubling rectification approach. It’s well-suited for small experiments and education, with straightforward wiring but limited output power compared to higher-voltage modules.
DORHEA 3Pcs DC 6V-12V to 1000kv High Voltage Modules
Brand: DORHEA. A three-pack designed around Tesla-coil-inspired principles, delivering 500kV–1000kV outputs from a 6–12 V input range. They emphasize high discharge intensity with a relatively simple peripheral circuit, ideal for educational demonstrations and controlled experiments with strict safety oversight.
Buying Guide: Key Purchase Considerations
- Input voltage and current: Ensure your power source can reliably supply the module’s voltage and current requirements. Higher output modules commonly need robust current availability to maintain stable operation.
- Output voltage and safety: Voltage levels in the hundreds of kilovolts demand rigorous insulation, secure housing, and safe work practices. Verify the maximum safe discharge distance and protective measures provided by the design.
- Module count and pricing: Packs (like 2-piece or 5-piece sets) can be cost-effective for experiments, but review consistency between units and any variation in performance.
- Wiring and cabling: Check cable lengths and color conventions (positive/negative). Clear labeling reduces wiring errors during assembly and testing.
- Applications and limits: These modules are intended for educational demonstrations and controlled experiments. They are not replacement high-power power supplies and should be used with appropriate test loads and arcing gaps.
- Safety features: Look for built-in protective housings, discharge procedures, and clear safety instructions. Always employ non-conductive enclosures and personal protective equipment when testing high-voltage units.
- Applicability to experiments: If you need pulsed high voltage with short discharge gaps, designs inspired by Tesla coils may suit your project. For simple spark-gap demos, lower voltage modules may suffice with proper safety.
To maximize safety and performance, plan experiments in a non-conductive workspace, use insulated tools, and keep passive components or liquids away from high-voltage sections. Document test parameters and monitor arc behavior under controlled conditions.
