We design and manufacture split‑core current transformers, Rogowski coils,and current and voltage sensing components for non‑intrusive measurement in industrial and power systems.
Split‑core and solid‑core current transformers covering compact, panel‑mounted and high‑current designs for building energy monitoring, sub‑metering, and power distribution applications.
Flexible Rogowski coils for non‑intrusive measurement of high currents, ideal for complex installation environments, large conductors, and transient current monitoring.
Current transducers with voltage or current signal outputs for real‑time current measurement, widely used in power monitoring, automation control, and industrial measurement systems.
Voltage transducers for accurate voltage measurement and signal conversion, supporting monitoring and control functions in power distribution and energy management systems.
Leakage current sensors designed for residual current monitoring and protection in electrical systems, suitable for equipment safety, insulation monitoring, and fault detection applications.
Power transformers for voltage conversion and power supply applications, supporting stable operation in industrial, commercial, and electronic equipment.
Voltage transformers providing electrical isolation and voltage scaling for measurement, protection, and monitoring applications in power systems.
High frequency transformers optimized for switching power supplies and high‑frequency circuits, offering compact size, high efficiency, and reliable performance.
Common mode chokes designed for electromagnetic interference suppression, improving signal integrity and EMC performance in power and electronic circuits.
Founded in 1992, YHDC is a professional manufacturer and supplier of current sensing components with long-term experience in industrial and OEM supply.

Engineering and Technical Support
YHDC maintains an experienced engineering team supporting product development, application evaluation and technical integration.
This enables efficient communication during project selection, testing and long-term product use.
YHDC operates ISO-certified quality management systems and follows controlled production and inspection processes.
Selected product models are UL certified, and non-UL certified products are designed and manufactured in accordance with UL material and safety requirements.
Products also comply with major international standards such as CE and RoHS.
With in-house mold design, development and manufacturing resources, YHDC supports OEM and custom current sensing solutions. This allows faster product adaptation, controlled tooling processes and reliable long-term supply for customized projects.
YHDC primarily works directly with customers while supporting regional sales and authorized distribution where appropriate, ensuring consistent quality and manufacturer-controlled support worldwide.
With its own warehouse facilities in Europe, YHDC supports stable inventory management and shorter delivery times. This helps customers reduce lead time risks and supports reliable long-term supply planning.
High performance products for the satisfied customers with professional services.
