HIC-C21 series current sensors are measurement modules that use a Hall closed loop (magnetic balance) principle to convert the measured current into an output current or voltage that follows proportionally. The primary and secondary sides are highly insulated. It has the characteristics of high accuracy, 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 electric power, petroleum, coal mining, chemical, railway, communications, building automation and other industries.
The HIC-C21 series current sensor uses a Hall‑closed‑loop (magnetic balance) principle to convert measured current into proportional current or voltage output while providing high isolation between primary and secondary sides. It offers high accuracy, linearity, compact size and stable long‑term operation for power, oil, mining, chemical, railway, communication and building‑automation applications.
