High-precision components engineered for reliability and accuracy in global power networks.
Founded in 1993, Fujian Smrtr Technology Co., Ltd. (Zentar®) has established itself as a global leader in the manufacturing of magnetic components for electrical safety and power measurement. With our primary operating facilities in Xiamen, we employ a dedicated workforce of approximately 410 professionals committed to engineering excellence.
Our expertise spans across consulting, design, and high-volume manufacturing of current transformers, RCD fused connection units, and wireless energy monitoring systems. We don't just supply parts; we provide integrated solutions that empower smart cities and industrial automation.
The global demand for Wireless Energy Monitoring Systems is witnessing an unprecedented surge, driven by the worldwide transition toward carbon neutrality and the rapid adoption of Industry 4.0. As businesses and governments strive to meet ESG (Environmental, Social, and Governance) targets, the ability to monitor energy consumption in real-time has shifted from a "luxury" to a "critical operational requirement."
In the current industrial landscape, traditional wired monitoring systems are being phased out due to high installation costs and lack of scalability. Wireless solutions—utilizing technologies like Zigbee, LoRaWAN, and NB-IoT—offer the flexibility needed for retrofitting older factories and scaling smart city infrastructures. From the bustling industrial hubs of Southeast Asia to the strictly regulated energy markets of Europe and North America, the need for accurate, wireless data acquisition is universal.
The global smart meter market is projected to grow significantly as utility companies upgrade aging infrastructure to support bidirectional energy flows from renewable sources.
Modern systems now integrate AI to predict load peaks and identify equipment failures before they occur, shifting energy management from reactive to proactive.
With the rise of BESS (Battery Energy Storage Systems), monitoring the health and efficiency of high-voltage battery containers has become a top priority for global procurers.
Our 40,000-square-meter facility is equipped with state-of-the-art automation to ensure every component meets international standards.
Our R&D capability is led by a team of distinguished professors and 20 senior engineers who continuously innovate to provide workable solutions. Since implementing ISO9001 in 2002 and upgrading to IATF 16949, we have ensured that our quality control procedures are among the most rigorous in the industry. With an annual production capacity of 50 million magnetic components, we are built to handle the world's largest OEM/ODM requirements.
Large manufacturing plants use our split-core current transformers and Rogowski coils for cost allocation across different departments, enabling precise energy budgeting.
Smart office towers integrate our Zigbee DIN rail meters to monitor HVAC and lighting systems, reducing operational costs by up to 30% through peak load analysis.
Our zero-phase current transformers are essential for fire monitoring and electrical fault protection in urban power grids, ensuring public safety and infrastructure longevity.
As a leading Chinese manufacturer, we offer a unique combination of technological sophistication and supply chain efficiency. Global procurers seek our services because we provide:
From home energy storage to industrial-grade high-voltage sensors.
