This pair targets a higher input voltage while delivering extremely high output levels, suitable for showcasing Tesla-coil style pulsed behavior. The stated output range emphasizes heavy-duty voltage generation with corresponding high-current considerations. Cable lengths are listed to help integrate into test benches and arc demonstration setups.
GODIYMODULES DC 12V 15000V to 20KV

This module offers a more modest and adjustable high voltage range, making it accessible for beginners to observe voltage ramp effects safely. It provides a straightforward wiring scheme with clear input and output polarity guidance, which helps when teaching basic HV concepts and safety practices.
DORHEA 3Pcs DC 6V-12V to 1000kv High Voltage Generator

Three modules in a compact set focus on boosting from standard low-voltage supplies to very high voltages. They emphasize a Tesla-coil-inspired approach with high-voltage pulsed outputs. The kit format can be useful for classroom demonstrations or hands-on projects requiring multiple modules to explore pulse behavior and discharge characteristics.
GODIYMODULES 2Pcs High Voltage Generator 3V-6V

This 2-pack option reiterates a low-input, high-output concept, ideal for paired experiments or parallel demonstrations. It emphasizes a pulse-style high-voltage output and provides basic connectivity guidance (e.g., input and output wiring conventions) to support safe handling and setup in controlled environments.
Buying Guide: Key Considerations For Selecting A High Voltage DC Generator
When choosing a high voltage DC generator for educational or hobby use, consider these factors to ensure safe and effective performance:
- Input voltage range: Match your power source. Lower voltages can be safer but may limit achievable output, while higher input ranges enable greater voltage amplification.
- Output voltage and pulse type: Decide whether you need a continuous high voltage, or pulsed/dielectric discharge outputs for demonstrations such as spark gaps or arc pulses.
- Current capability: High voltage devices still consume current. Ensure power supply and wiring can handle the current without overheating or insulation damage.
- Safety features and handling: High voltage products require strict safety protocols, insulated enclosures, and supervision during use. Look for clear wiring labels and protective accessories where available.
- Build and form factor: Some modules come as single boards, others as multi-pack sets. Consider space, mounting options, and ease of integration into test benches or educational kits.
- Documentation and wiring conventions: Clear wiring colors (positive/negative) and voltage ranges help reduce setup errors. Ensure you have access to documentation for safe operation.
- Discharge and insulation: High-voltage applications demand careful attention to discharge paths and insulation distance to prevent unintended arcing or shock.
- Educational value vs risk: For classrooms or self-study, prioritize kits with robust safety notes, accessible instructions, and visible limits on discharge distance and voltage.
- Warranty and support: Check for vendor support, return policies, and compatibility with common power supplies or test equipment.
