HIA-C02 series current sensor is a measurement module that converts the measured current into an output current or voltage in proportion to the Hall closed-loop (magnetic balance) 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 adapt to various working environments. It is widely used in power, petroleum, coal mining, chemical industry, railway, communication, building automation and other industries for system control and detection of electrical equipment.
