Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Voltage Regulation & Conversion: A 100kVA dry-type auto transformer designed to step down 440V input to 220V output while maintaining stable power distribution for three-phase systems.
  • Efficient Energy Transfer: Utilizes a toroidal coil structure and aluminum winding material to ensure high efficiency, minimal energy loss, and seamless phase matching in industrial and commercial applications.

Key features

  • 1. Advanced Material Technology for Durability

    • With an aluminum coil structure and toroidal design, achieve efficient heat dissipation and lightweight construction compared to traditional copper-wound transformers*. The corrosion-resistant metal body ensures long-term reliability in industrial environments.

  • 2. Precision Voltage Monitoring for Control

    • With built-in analog voltage meters, monitor real-time input/output voltage levels for precise adjustments, offering greater operational transparency than fully digital interfaces*. Ideal for maintaining stability in critical systems like manufacturing equipment.

  • 3. High-Capacity Performance for Heavy Loads

    • With a 100kVA rated capacity, handle demanding applications requiring 3-phase power conversion from 440V to 220V or other output ranges, outperforming standard 50kVA models in output capability*. The dry-type design ensures safe operation even under continuous use.

  • 4. Industrial-Grade Versatility for Diverse Scenarios

    • With a robust 3-phase auto-transformer design, deliver stable power conversion for industrial facilities, data centers, or commercial spaces, unlike single-phase units limited to lighter loads*. The casters enable easy relocation for flexible deployment.

  • 5. Certified Compliance for Global Use

    • With CE and RoHS certifications, meet EU safety and environmental standards for commercial deployment, ensuring compatibility with regulated industries like electronics manufacturing*.

Supplier's note

  1. Technical Breakthroughs:

    • Autotransformer Design: Reduces size and cost by sharing coils between input/output, enabling compact yet powerful solutions.
    • Toroidal Coils: Cut energy loss by 20% compared to traditional designs, enhancing efficiency in high-load scenarios.
    • CE/RoHS Compliance: Ensures safe operation in regulated industries like healthcare or electronics manufacturing.

  2. Version Selection Guide:

    • Base Model: Ideal for standard industrial applications (e.g., small factories) requiring reliable 100kVA capacity.
    • Advanced Model: Choose for medium-scale facilities needing extended overload tolerance (e.g., 24/7 manufacturing plants).
    • Pro Model: Best for high-demand environments (e.g., data centers) where ultra-precise voltage regulation and minimal noise are critical.

With the Pro Model’s ±1.5% voltage regulation, you can ensure stable power delivery to sensitive equipment, reducing downtime. Pair its low noise (55 dB) with the casters for seamless integration into noise-sensitive areas like hospitals.
