Product Overview
High Precision Current Sensors are advanced devices designed to measure AC and DC currents with exceptional accuracy and stability. They convert the current into a proportional electrical signal for precise monitoring, control, and protection. Using technologies such as Hall effect, fluxgate, or zero-flux methods, these sensors achieve high linearity, low offset drift, and fast response. They are widely used in power electronics, renewable energy systems, smart grids, industrial automation, and electric vehicles. With strong anti-interference capability, wide bandwidth, and compact design, high precision current sensors ensure reliable performance in demanding applications requiring accurate and consistent current measurement.
