In the era of Smart Grids and Industry 4.0, Miniature PCB Mounting Current Transformers have become indispensable. Globally, the demand is surging as power distribution moves toward micro-monitoring. Industries in North America and Europe are prioritizing energy efficiency, necessitating the integration of high-precision CTs directly onto circuit boards for real-time data acquisition.
Miniaturization is no longer just an option—it is a requirement. Current trends show a shift toward 0.1 and 0.2 accuracy class sensors that can handle DC components (DC immunity). As EV charging infrastructure and IoT smart home devices proliferate, the need for transformers that combine compact size with high galvanic isolation is at an all-time high.
Global enterprises are seeking "Turnkey Solutions." They require manufacturers who can provide not just a component, but a certified part that meets international standards like IATF 16949. Reliability, short lead times, and the ability to customize turn ratios (e.g., 1000:1, 2500:1) are the top priorities for modern procurement officers.
Fujian Smrtr Technology Co., Ltd. (Zentar®) is a world-class manufacturer of magnetic components. Founded in 1993, we have dedicated over three decades to the R&D and production of high-precision current transformers. With our main operating facilities in Xiamen, we employ a dedicated workforce of approximately 410 experts, including a core R&D team led by professors and 20 senior engineers.
Our expertise spans across consulting, design, and manufacturing of CTs, RCD fused connection units, and wireless energy monitors. We don't just manufacture; we innovate solutions that connect the future of electrical safety and power metering.
Our PCB mount CTs are the heart of smart electricity meters, providing Class 0.1 accuracy for billing-grade measurement. With DC immune capabilities, they ensure stable performance even in distorted current environments.
Designed for Residual Current Devices (RCD), our sensors detect minute leakages, providing critical protection against electric shock and electrical faults in residential and industrial settings.
As the electric vehicle market grows, our transformers provide dynamic energy consumption monitoring and peak load analysis for EVSE, ensuring safe and efficient power delivery.
Integration into motor control centers and sub-metering systems allows for predictive maintenance and cost allocation by monitoring individual equipment power signatures.
As a leading Chinese manufacturer, Smrtr Technology leverages high-end infrastructure and automated systems. From automatic winding to laser marking, we ensure every unit meets the highest reliability standards before reaching our global clients.
Our team, led by professors and senior engineers, provides continuous technical support and workable solutions for complex magnetic designs.
Implementing ISO9001 since 2002 and evolving under IATF 16949, we guarantee products that pass the most rigorous electrical safety standards.
With a 40,000 sqm workshop and ERP-managed production introduced in 2008, we ensure high-volume capacity and short lead times.
