Voltage sensor AC

High‑Precision AC Voltage Sensor – 50/60 Hz, Linear Output

This compact AC voltage sensor delivers accurate measurement of three‑phase or single‑phase line voltages up to 600 V AC, with a fully isolated, 5 V analog output that is readily compatible with PLCs, data loggers, and microcontrollers. Built on a high‑resolution Hall‑effect transducer, the module offers excellent temperature stability and minimal phase shift, making it ideal for real‑time power monitoring and energy management systems.

With a low output noise of <1 mV and a linearity error of less than ±0.5 % FS, the device guarantees dependable performance in harsh industrial environments. The sensor’s integral 6‑bit SPI interface enables easy configuration of gain, range, and calibration, while the rugged enclosure protects against vibration and electromagnetic interference.
