Supplier's note

  1. Three Technical Breakthroughs:

    • Amorphous/Nanocrystalline Composite: Combines the high permeability of amorphous alloys with nanocrystalline stability for unmatched efficiency.
    • Ultra-Low Core Loss: 20% lower than ferrite cores, enabling reliable operation in high-temperature environments.
    • Scalable Permeability: Adjustable material ratios allow permeability tuning to match specific application needs.

  2. Version Selection Guidance:

    • Base Model: Ideal for standard industrial applications (e.g., low-frequency inverters) where cost-efficiency is prioritized.
    • Advanced Model: Optimal for mid-range power systems (e.g., solar inverters) requiring 15 kHz operation and moderate current handling.
    • Pro Model: Designed for high-demand scenarios like electric vehicle chargers, where 20 kHz frequency and 20A current capacity are critical.

With the Pro model’s 100,000 permeability, you can achieve 40% smaller coil sizes while maintaining magnetic efficiency. Its 10 mW/cm³ core loss ensures stable performance even in high-temperature industrial settings. Pair this with its 20A rating to handle demanding power conversion tasks seamlessly.
