Three-phase Four-wire True RMS AC Voltage Transducer
This device is a 3-phase 4-wire AC voltage isolation transducer. It is designed for application where AC voltage waveform is not purely sinusoidal. It’s more precise and accurate than other transducers. The product is widely used in non-standard waveform distortion sine wave real-time signal detection and monitoring.
