Powering the Future with Precision – Our Story

For over 15 years, we’ve been at the heart of electrification — designing and manufacturing high-performance current transformers (CTs) trusted by some of the world’s most demanding OEMs, including BYD, XiaoMi, Huawei, Stellantis, Toyota, and the VW Group. From low-current sensing in consumer electronics to high-current measurement in EV traction systems, our technology roadmap reflects a steady climb in performance, integration, and reliability:

2009–2013: Compact CTs for telecom & consumer electronics – precise, stable, and cost-efficient.

2014–2018: Mid-range CTs for industrial and energy applications – higher saturation points, improved thermal stability.

2019–Present: High-current, high-frequency EV-grade CTs – optimized for battery management systems (BMS), on-board chargers (OBC), and bidirectional DC fast charging (V2X).

Next Horizon: Ultra-compact, wide-bandwidth CTs enabling next-gen SiC/GaN-based EV power architectures.

Why Our CTs Win in EV Applications:

    • R&D Strength: Dedicated engineering centers with advanced simulation, prototyping, and in-house calibration labs.
    • Performance-Driven: Low phase error, excellent linearity, and stable operation under high thermal stress.
    • Cost Advantage: Competitive pricing without compromising quality, backed by lean manufacturing.
    • Supply Chain Resilience: Multi-site production in China, Vietnam, and Thailand（Plan to bring in) — ensuring supply continuity and tariff flexibility.
    • EV-Ready Quality: IATF 16949, ISO 9001, and ISO 14001 certified facilities with 100% end-line testing.
