AEDIKO EI-14 Audio Transformer (10 pcs)
The AEDIKO EI-14 set features a 1:1 ratio with 600:600 Ohm impedance, designed for audio isolation and voltage amplification tasks. The transformers are noted for high-quality construction, a broad pass-band, and large original winding inductance with reduced leakage inductance to minimize hysteresis losses. Applications include audio isolation, signal conditioning, and situations where stable, low-noise coupling is essential. In practice, these units can form the core of isolation stages in test benches and signal paths, reducing ground loop issues and external interference while preserving signal integrity.
Key considerations: ensure the transformer’s impedance matches the circuit’s expectations, verify sufficient insulation for the expected voltage, and account for thermal dissipation in continuous operation. Safety margins should be evaluated for higher-voltage contexts, and physical spacing from high-voltage conductors kept to prevent arcing.
AEDIKO 5pcs High Voltage Generator DC 3v-6v to 400kV Boost
This AEDIKO module is a compact high-voltage generator capable of boosting DC input from 3–6 V up to approximately 400 kV. It uses a step-up approach suitable for experiments, arc ignition demonstrations, and educational demonstrations of high-voltage effects. The unit specifies input current requirements (2–5 A) and a safe operating range with a 10–20 mm discharge distance in air. While it enables high-voltage output, it demands rigorous safety practices, appropriate enclosure, and robust insulation to avoid dangerous exposure to personnel and flammables.
Important safety notes: high-voltage testing should occur in non-flammable environments, with proper PPE, eye protection, and remote operation where feasible. Do not use near conductive materials or liquids, and keep a safe distance during operation. This module is intended for experienced hobbyists or professionals familiar with high-voltage safety norms and arc phenomena.
AEDIKO EE-14 Audio Transformer (10 pcs)
The AEDIKO EE-14 series emphasizes higher impedance with an AC impedance ratio of 1300:8 Ohms, offering robust performance for voltage amplification and power transfer in audio and signal processing tasks. The design highlights include a wide pass-band and a winding inductance that supports stable operation with minimal hysteresis loss. These transformers are well-suited for isolation in audio circuits, prototyping isolated signal paths, and projects requiring clean coupling between stages while maintaining signal fidelity.
When integrating an EE-14 transformer into a system, users should confirm the impedance match with subsequent stages, verify inter-winding insulation ratings for the operating voltages, and evaluate the thermal profile under expected load conditions. Proper mounting and strain relief are recommended to protect wire connections from mechanical stress.
AEDIKO 10pcs EE-14 Audio Transformer (1080:1080 Ohm)
This variant presents an impedance profile of 1080:1080 ohms within the EE-14 family, designed for high-frequency applications and precise voltage amplification needs. It maintains the brand’s emphasis on high-quality materials, large original winding inductance, and low leakage inductance to minimize hysteresis effects. Use cases include isolated signal paths in RF or high-frequency testing benches where consistent coupling is required, and the transformer acts as a buffer between test equipment and the device under test.
Design considerations include ensuring the primary and secondary windings are adequately insulated for the operating voltage range, accounting for parasitic capacitance that may affect high-frequency performance, and providing adequate airflow or heat sinking in continuous use scenarios. Safety practices should always be observed when operating at elevated voltages.

When choosing a high voltage transformer or booster, consider: the voltage range and current capability; insulation class and safety certifications; physical form factor and mounting; thermal management; and how well the device fits into your testing or prototyping workflow. For isolation needs specifically, verify that the transformer provides galvanic isolation between primary and secondary and that insulation is rated for the intended operating voltage and environment.
Buying Guide: Key Purchase Considerations
- Voltage and current requirements: Determine the required output voltage range and current capacity for your application to select a transformer with adequate power handling.
- Isolation and insulation: Prioritize galvanic isolation ratings and insulation classes appropriate for your operating voltages. Consider creepage and clearance distances in your enclosure design.
- Impedance and impedance matching: Ensure impedance specifications align with your circuit’s input and load to avoid signal loss or overheating.
- Frequency response: For audio-oriented transformers (like EI-14 and EE-14 variants), confirm pass-band and frequency performance match your signal bandwidth.
- Safety and compliance: High-voltage work demands protective enclosures, interlocks, and adherence to local regulations. Use PPE and implement remote operation when possible.
- Physical design: Assess size, mounting options, lead lengths, and thermal dissipation features to fit your build and maintain reliability.
- Manufacturer support and documentation: Review available datasheets, usage guides, and safety instructions to ensure proper integration into your project.
In summary, the selection above covers a mix of isolation-oriented audio transformers and high-voltage booster modules. Depending on whether your focus is signal isolation, voltage amplification, or arc-generation demonstrations, carefully weigh the electrical specifications, safety considerations, and integration needs before purchasing. Always design experiments with failsafes, proper insulation, and controlled environments to minimize risk when working with high voltages.
