2pcs DC-DC High Voltage Boost Converter 8-32V to ±45V-390V
Module Properties: Non-isolated step-up module with a wide input range and high-voltage output. This boost converter supports 8-32V input (default 10-32V) and can regulate output across a broad high-voltage spectrum. Ideal for capacitor charging experiments or projects requiring ± high voltage with compact form factor. The design incorporates a ZVS (zero-voltage switching) approach to improve efficiency and reduce stress on the input supply. Consider thermal management and proper insulation when operating at higher voltage settings.
170V DC High Voltage Power Supply Module Boost
DC-DC boost module using a 3845 scheme suitable for vacuum tubes and nixie indicators. Input 10-24V, adjustable output 90-250V. It can drive more than ten vacuum tubes with light heat generation, eliminating the need for extra cooling. Users should note that higher output voltages reduce maximum current and overall efficiency. When set to 170V, the module supports up to 25mA output current, which is typical for tube indicators and related displays.
DC 12V Power Supply Driver Transformer 15W IP67
Brands often position this 12V LED power supply driver as a compact, waterproof option for outdoor or damp indoor installations. It accepts AC input in a wide range (100-265V) and outputs a stable 12V DC, enclosed in an aluminum body for superior heat dissipation. The IP67 rating ensures reliable outdoor operation, making it suitable for LED strips, signs, and display modules used in challenging environments. Use case versatility makes it a strong candidate for signage and architectural lighting projects.
2Pcs DC-DC High Voltage Boost Converter 8-32V to ±45-390V
This packaging includes two identical high voltage boost converters configured for 8-32V input with a wide output range of ±45V to 390V. The back-side jumper selects the input window (default 10-32V). Each unit can provide up to 5A input current, delivering substantial high-voltage output capability for capacitor charging or Tesla-coil-inspired demonstrations. As with any high-voltage setup, ensure proper insulation, secure wiring, and adherence to safety practices to prevent shock hazards.
2pcs 3.6-6V to 20kV High Voltage Boost Module
This module uses a Tesla-coil-inspired principle to generate very high voltages from a small DC input. Operating from 3.6-6V, it can produce up to 20kV high-voltage pulses suitable for demonstrations, discharge experiments, or HV testing. The design emphasizes a compact footprint and straightforward wiring, but the high voltage requires strict safety measures, including insulating surfaces and short, controlled discharge paths. Suitable for hobbyists exploring high-voltage physics concepts.
Buying Guide: Key Considerations For High Voltage Power Supply Modules
When selecting a high voltage power supply module, consider these dimensions to ensure a safe, effective fit for your project:
- Voltage range and accuracy: Ensure the module provides the required voltage with adequate regulation for your application. Narrow tolerance can affect sensitive circuits.
- Input voltage and range: Check whether the module can operate from the power source you have (DC vs AC, common battery or wall power). Some modules require specific input ranges or protection features.
- Output current and power: High voltage modules trade current for voltage. Verify the maximum current at your target voltage to avoid damage or overheating.
- Thermal management: High voltage operation generates heat. Look for modules with good heat dissipation, heat sinks, or water resistance if used outdoors or in enclosed spaces.
- Isolation and safety: Non-isolated designs can introduce safety risks. Ensure proper insulation, enclosures, and safe discharge paths when operating HV equipment.
- Build quality and components: Quality transformers, switching circuitry, and insulation materials influence reliability and longevity—especially in ZVS configurations.
- Size and form factor: Compact modules are easier to integrate into portable projects, but may limit heat sinking or connector options.
- Safety features: Consider short-circuit protection, over-voltage protection, and clear documentation for handling high voltage safely.
- Applications compatibility: Nixie tubes, vacuum tubes, LED signage, or capacitor charging have different electrical demands; match the module to your intended load.
- Regulatory and usage considerations: Some HV modules are intended for hobbyist demonstrations. Ensure compliance with local safety standards and usage guidelines.
In evaluating options, compare the total system requirements—input supply availability, desired output voltage, and the maximum safe operating current. For experiments with vacuum tubes or nixie indicators, modules with stable high voltage and low heat output are typically preferred. For signage or LED-based projects, IP-rated enclosures and robust heat management can extend service life. Always implement rigorous safety practices when dealing with high voltage, including proper insulation, protective gear, and informed handling procedures.
