Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Frequency Power Conversion: Designed for audio amplifiers and transformer applications, enabling precise AC voltage conversion with minimal distortion and energy loss.
  • Efficient Energy Transfer: Utilizes CRGO-grade FeSi silicon steel cores for superior magnetic permeability, ensuring high efficiency and reduced heat generation in audio systems.

Key features

  • 1. Advanced Material Technology

    • With a FeSi Silicon Steel CRGO core and silicone composite insulation, you can achieve high magnetic permeability and corrosion resistance, reducing energy loss by ~20% compared to conventional silicon steel cores*. The toroidal design further minimizes magnetic leakage for efficient power transfer.

  • 2. Customizable Interactive Design

    • With its toroidal shape and modular winding configuration, you can adapt the transformer to diverse audio applications, offering 30% more space efficiency than traditional E-core designs*. The multiple wire connections enable flexible voltage customization for amplifiers and industrial systems.

  • 3. Precision Performance Parameters

    • With ±1% tolerance and high-frequency compatibility, you can ensure accurate voltage regulation and stable output, delivering 5x greater precision than standard 5% tolerance models*. This guarantees reliable performance in sensitive audio and industrial setups.

  • 4. Industrial-Grade Scenario Solutions

    • With rugged industrial magnet construction, you can operate continuously in commercial audio systems or industrial environments, handling 2x higher load capacities than home-use transformers*. The compact design suits space-constrained applications like amplifiers and power supplies.

  • 5. Compliance with Safety Standards

    • With materials designed to meet industrial safety requirements, you can ensure reliable performance in regulated environments. While specific certifications (e.g., RoHS, ISO) are subject to manufacturer confirmation, the core’s silicone insulation and ferrite composition align with eco-friendly and high-temperature standards.

Supplier's note

  1. Technical Breakthroughs:

    • CRGO Core: Reduces core losses by 20% compared to standard silicon steel, enhancing energy efficiency.
    • Multi-layer Insulation: Achieves 30 dB EMI shielding—exceeding IEC 61800-3 standards—critical for noise-sensitive audio systems.
    • Customizable Windings: Adjustable turns ratio allows precise voltage matching (e.g., 1:10 step-up for amplifier outputs).

  2. Version Selection Guidance:

    • Base Model (M0): Ideal for small audio devices (e.g., portable speakers) needing basic power conversion.
    • Advanced Model (M3): Targets mid-range industrial systems (e.g., studio amplifiers) requiring balanced power and EMI control.
    • Pro Model (M5): Designed for high-power applications like industrial inverters or professional audio setups, where 95% efficiency and 30 dB EMI reduction ensure reliability under heavy loads.

With the Pro’s tripled EMI shielding compared to industry benchmarks, users can safely deploy it in environments with dense electromagnetic interference. Pair its 200W capacity with high-gauge windings to handle peak currents without saturation.
