Power Transformer Step up Transformer 220 400 690 Volts

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Voltage Conversion: Designed as an autotransformer to step up/down voltages (e.g., 220V to 12V/36V/380V) for power distribution and device compatibility.
  • Efficient Energy Transfer: Utilizes copper windings and EI core structure for high efficiency, low energy loss, and stable performance across 50/60Hz frequencies.

Key features

  • 1. Material Technology: Copper Windings and Durable Metal Construction

    • With copper windings and a corrosion-resistant metal body, ensure efficient power transfer and long-lasting durability. Copper enhances conductivity compared to aluminum, reducing energy loss, while the robust metal casing withstands high temperatures and physical stress*.

  • 2. Interactive Design: Color-Coded Wiring for Safe and Intuitive Use

    • With color-coded wiring (red for primary/220V, blue for secondary/12V), reduce connection errors and improve safety during installation. This design simplifies setup for users of all technical skill levels compared to non-coded alternatives*.

  • 3. Performance Parameters: Autotransformer Efficiency and Multi-Voltage Flexibility

    • With an autotransformer design, achieve up to 95% efficiency* and compact size compared to traditional isolation transformers. Supports multi-voltage outputs (12V/36V/380V) and 50/60Hz compatibility, adapting to global power systems and diverse applications like lighting or small electronics.

  • 4. Scenario Solutions: Versatile Step-Up/Step-Down Applications

    • Designed for step-up and step-down scenarios, this transformer efficiently powers devices requiring 12V (e.g., LED lighting), 36V (low-voltage appliances), or 380V (industrial equipment). Ideal for home, commercial, or light-industrial use where compact, reliable voltage conversion is critical.

  • 5. Certification Standards: Compliance with Safety and Industry Norms

    • Complies with international safety standards (e.g., IEC/UL certifications*) for secure operation. Built with food-grade copper windings and flame-retardant materials, ensuring environmental and user safety.
