The HIB-C15 series current sensor is a measuring module that converts the measured current into a proportional output current or voltage using the Hall closed-loop principle. The primary and secondary windings are highly isolated. It has the characteristics of high precision, high linearity, high integration, small structure, simple structure, long-term stable operation and adaptability to various working environments. It is widely used in the system control and testing of electrical equipment in the fields of power, petroleum, coal mine, chemical industry, railway, communication, and building automation.
