The FHS-004 High stability copper shunt is a precision shunt designed for industrial applications with performance and reliability. The product is made of high-purity copper material, which ensures its low loss and high accuracy in current shunt. Its design goal is to provide long-term stability and high-precision current measurement, suitable for a variety of industrial scenarios, such as power management systems, motor drives, and battery management systems. The FHS-004 High stability copper shunt uses advanced manufacturing processes, including electron beam welding (EBW) technology, to ensure the high reliability and low thermal resistance of the shunt. Its resistance value accuracy is as high as ±5%, and it can still maintain stable performance under temperature conditions (-50°C to 150°C). In addition, the shunt also has low power loss characteristics, less than 50 milliwatts, which is very suitable for industrial applications that are sensitive to energy consumption. The FHS-004 High stability copper shunt also has good environmental adaptability and can work stably in harsh industrial environments. At the same time, it supports a variety of mounting methods, including welding terminals and integrated leads, which is convenient for users to customize according to specific needs. This product is not only suitable for traditional power metering equipment, but also can be used in emerging fields such as new energy vehicles, communication equipment and inverters. Its high precision and high reliability make it an ideal choice for industrial automation and power systems, providing users with a safe and reliable current measurement solution.
