The global power measurement industry is undergoing a paradigm shift. As the world transitions toward Smart Grids and Industry 4.0, the demand for high-precision power meters has never been higher. Today's industrial landscape requires more than just reading numbers; it demands real-time data analytics, power quality monitoring, and seamless integration with IoT ecosystems.
Modern power meters now serve as critical nodes in smart grids, providing bidirectional communication for localized energy management and grid stability.
Global corporations are utilizing precision metering to meet stringent ESG (Environmental, Social, and Governance) goals, tracking carbon footprints via precise kWh data.
The surge in solar and wind farms requires high-accuracy DC and AC measurement to manage fluctuating power inputs and high-efficiency conversion.
Modern meters process data at the "edge," reducing latency in industrial automation and protecting sensitive equipment from voltage spikes.
Wireless technologies like Zigbee, NB-IoT, and RS485 Modbus allow facilities to manage energy assets from anywhere in the world.
Founded in 1993, Fujian Smrtr Technology Co., Ltd. (Zentar®) has established itself as a cornerstone in the global power measurement and electrical safety industry. With over three decades of Experience, we have transitioned from a local manufacturer into a leading international supplier of magnetic components and precision energy monitoring solutions.
Headquartered in Xiamen, our state-of-the-art facility spans over 40,000 square meters and employs a dedicated workforce of approximately 410 professionals. Our Expertise is fueled by a high-caliber R&D team led by renowned professors and 20 senior engineers, ensuring that our technical solutions are always at the forefront of the industry.
Tailored solutions for diverse industrial and commercial environments.
Ideal for multi-tenant office buildings and shopping malls, enabling precise cost allocation and billing based on real-time consumption data.
Data centers require zero-failure power monitoring. Our Rogowski coils and CTs provide the high precision needed for PUE (Power Usage Effectiveness) analysis.
Integrate our Modbus-RTU 3-Phase meters into SCADA systems to monitor motor efficiency and prevent downtime through predictive maintenance.
As the electric vehicle market grows, our compact and high-efficiency transformers are vital for DC fast-charging stations and home wallbox units.
Our Zero Sequence Current Transformers are critical for RCD (Residual Current Device) applications, ensuring human safety and equipment protection.
Strict quality control from raw materials to final testing.
Our Reliability is backed by certifications such as ISO9001 (since 2002) and the rigorous IATF 16949 standard, which is essential for automotive and high-precision electronic manufacturing. Utilizing automatic winding machines, laser markers, and eight-axis winding systems, we ensure every component—from split-core current transformers to Rogowski coils—meets the highest tolerances.
By leveraging ERP systems introduced in 2008, we maintain short lead times and strict quality control, making us the preferred factory for international OEMs and wholesalers.
Based in Fujian, we have direct access to the world’s most robust electronics supply chain, allowing us to source premium silicon steel and copper at competitive rates.
Unlike standard distributors, we offer Full Customization. Our team can design specific magnetic ring cores or energy monitors tailored to your unique voltage or frequency requirements.
With an annual capacity of 50 million magnetic components, we can scale production to meet the needs of massive infrastructure projects without compromising on precision.
We don’t just sell products; we provide workable solutions. Our senior engineers provide consulting on electrical safety and protection against electric shocks.
Our products are designed for the global market, ensuring compatibility with international standards for metering accuracy, including Class 0.5 and 0.5s requirements.
