HV-C54 series voltage sensor is a measurement module that uses the Hall closed-loop (magnetic balance) principle to convert the measured voltage into a current or voltage output that is proportional to the primary voltage. It has the characteristics of high accuracy, high linearity, high integration, small size, simple structure, long-term stability, and adaptability to various working environments. It is widely used in the system control and detection of electrical equipment in industries such as power, petroleum, coal mining, chemical, railway, communication, and building automation.
The HV-C54 series voltage sensor uses a Hall‑closed‑loop (magnetic balance) principle to convert the measured voltage into a proportional current or voltage output. It offers high precision, linearity, integration, compact size, and long‑term stability, making it suitable for power, petrochemical, mining, chemical, railway, communications, and building‑automation equipment.
The sensor supports AC, DC and mixed currents, with a measurement range of 100 V to 2500 V rms, output current of 0.01 A rms, and accuracy of ±0.7 % at 25 °C. It operates from –25 °C to +70 °C, stores at –45 °C to 185 °C, and complies with EN50178 and UL94‑V0 standards. Installation requires qualified personnel, proper wiring, and protection against dust, corrosion, vibration, and high temperature. This manual is written in Chinese.
