Product Overview
A High Accuracy Current Sensor is designed to precisely measure AC and DC current with minimal error and excellent stability. It converts the measured current into a proportional voltage or current signal for accurate monitoring and control. Using advanced technologies such as Hall effect or closed-loop zero-flux methods, it ensures high linearity, low temperature drift, and fast response. These sensors are widely used in power electronics, industrial automation, renewable energy systems, and electric vehicles. With high reliability, compact design, and strong anti-interference capability, high accuracy current sensors provide precise current measurement for efficient and safe system operation.
