FHS-002 High Precision Copper Shunt

FHS-002 High Precision Copper Shunt is a high-precision shunt made of high-quality copper and has  current measurement performance. This product is designed for applications that require high-precision current measurement, such as smart meters, charging piles, and industrial control systems. Its core advantage lies in the use of precision manganese copper resistor materials to ensure the low temperature coefficient and high stability of the shunt resistor, thereby achieving accurate current measurement. The shunt resistor of FHS-002 is made using electron beam welding technology, which ensures high consistency and long-term reliability of the resistance value. Its design supports a variety of current measurement ranges, suitable for current measurement needs from milliamperes to thousands of amperes, meeting the needs of different industrial and consumer electronic devices. In addition, the shunt also has good thermal stability and can maintain stable performance under temperature conditions, which is suitable for high-demand applications in industrial environments. FHS-002 High Precision Copper Shunt has become an ideal choice in the field of current measurement due to its high precision, low temperature coefficient and thermal stability. Whether it is used for charging piles, smart meters or industrial control systems, it can provide a reliable current measurement solution to ensure the Safety and accuracy of equipment operation.
