The HV-C04 series voltage sensor is a measurement module that converts the measured voltage into an output current or voltage that is proportional to the primary voltage using the principle of a Hall closed-loop (magnetic balance). The primary and secondary sides are highly isolated, have high accuracy, linearity, integration, small size, simple structure, long-term stable operation and adapt to various working environments. It is widely used in the system control and testing of electrical equipment in the power, petroleum, coal, chemical, railway, communication, building automation and other industries.
The HV-C04 series voltage sensor uses a magnetic‑balance principle to convert pressure into a proportional current output. It offers high precision, high stability, high integration and a compact size, making it suitable for applications in power, oil, chemical, railway, communications and building automation.
The manual details the sensor's electrical parameters, mechanical dimensions, connection pinout, environmental limits and handling precautions, allowing users to install and operate the device safely and accurately. This manual is written in Japanese.
