Fujian Smrtr Technology Co., Ltd. (Zentar®) is a premier global manufacturer specializing in magnetic components for electrical safety and power measurement. Founded in 1993, we have dedicated over three decades to engineering excellence. With our primary operating facilities in Xiamen, China, and a dedicated workforce of approximately 410 professionals, we have established ourselves as a cornerstone in the international sensor market.
Our expertise spans the consulting, design, and manufacturing of high-precision current transformers, RCD fused connection units, and wireless energy monitors. Led by distinguished professors and a team of 20+ senior engineers, our R&D capability ensures that we stay at the forefront of technological shifts, particularly in the realm of High Frequency Rogowski Coil Sensors. We don't just sell products; we provide workable solutions and technical support that empower global industries to monitor energy efficiency and ensure electrical safety.
The global industrial landscape is undergoing a massive shift toward electrification and digitalization. High Frequency Rogowski Coil Sensors have become indispensable in this transition. Unlike traditional current transformers (CTs) that rely on magnetic cores prone to saturation, Rogowski coils use an air-cored design. This allows them to measure high-speed transient currents and high-frequency harmonics with unparalleled linearity.
As power electronics evolve with Wide Bandgap (WBG) semiconductors like Silicon Carbide (SiC) and Gallium Nitride (GaN), the need for sensors that can operate in the Megahertz (MHz) range has skyrocketed. Modern power analyzers and lightning detection systems require sensors that can capture di/dt (rate of change of current) without distorting the signal. We are seeing a global trend toward miniaturization and integration, where flexible sensors are preferred for their ease of installation in tight spaces, such as EV charging stations and compact switchgears.
Our 40,000-square-meter facility is equipped with state-of-the-art automation to ensure every High Frequency Rogowski Coil meets stringent international standards.
Quality control is the heartbeat of Zentar®. Having implemented ISO9001 in 2002 and later upgrading to IATF 16949, we guarantee that our magnetic components are automotive-grade in reliability. Our infrastructure includes automatic soldering machines, laser markers for traceability, and advanced eight-axis winding machines that ensure the perfect uniformity required for high-frequency response accuracy.
As a leading Chinese supplier, we offer a unique combination of scale, speed, and technical sophistication. Global procurement managers from Europe, North America, and Southeast Asia look for three things: reliability, cost-efficiency, and customization. Zentar® delivers on all fronts:
Our sensors are applied in diverse environments globally. In Germany, they are used in high-precision welding power supplies. In the United States, they monitor lightning strikes on wind turbines. In Smart Cities across Asia, our split-core Rogowski coils facilitate sub-metering and peak load analysis for energy-efficient buildings. Whether it's high-voltage 36kv applications or handheld transducers for field technicians, our technology adapts to the local industrial need.
As we look toward a greener future, the role of High Frequency Rogowski Coil Sensors in energy efficiency monitoring cannot be overstated. From sub-metering cost allocation to dynamic energy consumption and peak load analysis, these sensors provide the data needed for automation and smart grid management. At Fujian Smrtr Technology, we are committed to "Connecting the Future Together." Our annual production capacity of 50 million magnetic components ensures that we can scale with your business, providing the protection against electric shock and electrical faults that the modern world demands.
