Encapsulated Transformer 220V to 15V 1VA Isolation Transformer

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Voltage Conversion & Isolation: Designed to step down 220V AC input to 18V output (56mA) with 1VA power capacity, providing electrical isolation for safe power distribution.
  • Dual Configuration: Functions as both an autotransformer (for efficient power transfer) and isolation transformer (to block ground loops and enhance safety in sensitive circuits).

Key features

  • 1. Durable Material Technology for Enhanced Safety

    • With a corrosion-resistant blue plastic housing and isolation design, ensure reliable insulation and protection against electrical shocks. This design surpasses non-isolated transformers in safety compliance for home and industrial use*.

  • 2. Compact and Efficient Coil Structure for Flexible Integration

    • With an EI/toroidal coil structure, achieve efficient power conversion and compact form factor, making it 30% smaller than traditional transformers* for seamless PCB mounting and space-constrained applications.

  • 3. Precision Performance for Low-Power Applications

    • With a 1VA power rating and 220V-to-15V output, reliably power low-current devices (e.g., sensors, appliances) while maintaining stable voltage conversion—ideal for applications requiring precise energy distribution.

  • 4. Versatile Scenario Solutions for Diverse Electronics

    • Designed for single-phase systems, this transformer supports both residential electronics (e.g., home appliances) and commercial low-power devices, offering continuous operation in environments where isolation and efficiency are critical*.

  • 5. Certified Safety and Quality Assurance

    • Certified to CE and SGS standards, guaranteeing compliance with international safety and quality benchmarks—ensuring reliability compared to uncertified alternatives*.
