Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Voltage Conversion: Step-down 415V to 380V for seamless power compatibility in industrial and commercial equipment.
  • Efficient Power Handling: 3-phase autotransformer design with toroidal coils ensures high efficiency, compact size, and minimal energy loss.
  • Robust Power Distribution: 40kVA capacity supports heavy-duty applications requiring stable voltage regulation and load management.

Key features

  • 1. Advanced Material Technology for Durability and Efficiency

    • With an aluminum-coil design and corrosion-resistant metal enclosure, you can ensure long-term reliability in industrial environments. Aluminum offers superior thermal conductivity compared to traditional copper, enhancing cooling efficiency while reducing weight by ~20%* compared to conventional transformers.

  • 2. Toroidal Coil Structure for Compact Performance

    • With a toroidal coil configuration, you can achieve space-saving installation and reduced energy loss. This design minimizes electromagnetic interference and noise, outperforming traditional E-I core transformers by up to 30% in efficiency* while maintaining a smaller footprint.

  • 3. Multi-Voltage Flexibility for Versatile Applications

    • With dual output voltage capabilities (415V/380V) and a 40kVA rated capacity, you can adapt to diverse power requirements. This step-down transformer delivers ~15% faster voltage regulation* than standard models, ensuring stable performance for heavy machinery or commercial systems.

  • 4. Industrial-Grade Safety and Monitoring Features

    • With analog voltage meters and built-in safety mechanisms (e.g., overcurrent protection), you can monitor real-time performance and prevent system failures. The robust ventilation slots and wooden pallet mounting provide ~40% better heat dissipation* and easier transport than non-industrial designs*.

  • 5. Compliance with Safety and Efficiency Standards

    • With a design aligned to industry safety protocols (e.g., IP23 protection, CE certification-ready), you can meet regulatory requirements for commercial and industrial use. Confirm specific certifications directly with the manufacturer for your region*.
