LMZC-10 High-Current Through-Core Instrument Transformer 415V 220V Flyback Topology for Indoor Competitive Wholesale

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Precision Current Measurement: Utilizes a flyback topology and dual copper windings to accurately monitor current in power systems, supporting voltages up to 415V/220V.
  • Non-Contact Through-Core Design: Enables safe installation around conductors without direct contact, ideal for high-voltage environments.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a copper and resin composite body, ensure long-term durability in harsh industrial environments. The non-conductive resin coating provides superior insulation compared to all-metal designs, reducing the risk of electrical faults.

  • 2. Through-Core Design for Seamless Installation

    • With a cylindrical through-core design, easily install around conductors without interrupting live circuits. The central opening allows compatibility with wires of various diameters, simplifying retrofitting in existing systems.

  • 3. High-Precision 10P10 Rating for Reliable Performance

    • With a 10P10 accuracy class, handle up to 10x rated current without saturation, ensuring stable operation during power surges. The 0.5 accuracy class guarantees precise measurements for critical monitoring applications.

  • 4. Versatile Flyback Topology for Commercial Use

    • Designed for indoor commercial and industrial settings, the flyback topology provides galvanic isolation and supports multiple output voltages (220V-480V), adapting to global power systems.

  • 5. IEC 60076 Certification for Global Compliance

    • With IEC 60076 certification, meet international safety and performance standards for power transformers. Ensures compatibility with over 150 countries' regulations for commercial and industrial use.
