The JU3-C55 series three-phase AC voltage transducer is a measurement module that converts the measured three-phase AC voltage into a proportional output of DC current or DC voltage signals corresponding to the three phases using the principle of electromagnetic induction (mutual induction). It has the characteristics of 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 industries such as power, petroleum, coal mining, chemical, railway, communication, and building automation.
The JU3-C55 series three‑phase AC voltage transmitter from Passion Technology converts three‑phase AC voltage into proportional DC current or voltage signals, offering high accuracy, linearity, and insulation for use in power, petrochemical, mining, and other industrial applications.
