The JU1-C52 series AC voltage transducer is a measurement module that converts the measured AC voltage into a DC current or DC voltage signal with a DC current or DC voltage signal proportional to the primary voltage using the principle of electromagnetic induction (mutual inductance). The primary and secondary sides are highly insulated, with high accuracy, high linearity, high integration, small size, simple structure, long-term stable operation and adaptability to various working environments. It is widely used in the system control and detection of electrical equipment in the power, petroleum, coal mining, chemical, railway, communication, and building automation industries.
This document introduces the JU1-C52 series alternating voltage transmitter, highlighting its high accuracy, linearity, compact size, and DIN‑rail mounting. It explains the principle of operation—using electromagnetic induction to convert AC voltage to proportional DC current or voltage signals—and lists typical application fields such as power, petrochemical, mining, and building automation.
The manual includes selection information, general parameters, mechanical and wiring diagrams, output characteristic curves, and detailed safety precautions. It specifies wiring terminal assignments, recommended load resistances, power supply requirements, and environmental limits for reliable installation and operation. This manual is written in Chinese.
