HDIB-C15 series DC current transducer is a measurement module that converts the measured DC current into a proportionally output DC current or DC voltage using the Hall effect and open loop measurement principle. The primary and secondary sides are highly insulated. It has the characteristics of high accuracy, high linearity, high integration, small size, simple structure, long-term stable operation and adaptability to various working environments. It is widely used in electrical equipment system control and testing in electric power, petroleum, coal mining, chemical industry, railway, communication, building automation and other industries.
