The HIA-C01 series current sensor is a measurement module that converts the measured current into a proportional current or voltage output using the Hall closed-loop (magnetic balance) principle. It features high accuracy, high linearity, high integration, small size, simple structure, long-term stable operation, and adaptability to various working environments. This current sensor is widely used in electrical equipment system control and detection in industries such as power, oil, coal mining, chemical, railway, communication, and building automation.
The HIA-C01 series is a Hall‑closed‑loop current sensor designed for measuring AC, DC and mixed currents up to 50 A rms. It features a compact PCB‑mountable design, high linearity, fast response and strong primary‑secondary isolation, making it suitable for power, oil, coal, chemical, railway, communication and building‑automation applications.
Key specifications include selectable current ranges (6 A, 15 A, 25 A, 50 A), a 5 V supply voltage, accuracy of 0.5 % (±0.2 % temperature coefficient), operating temperature from –40 °C to +85 °C, UL94‑V0 housing material, and a weight of about 10 g. Wiring must be performed by qualified engineers to avoid exposure of conductive parts and prevent damage. This manual is written in Chinese.
