Three phase four wire true RMS AC voltage transducer
This device is a 3-phase AC voltage isolation transducer. It is applied the principle of electromagnetic isolation and true RMS measurement. After True-RMS conversion, it can measure three-phase AC voltage non-sinusoidal alternating signal RMS, isolated and linearly output standard voltage or current signal. The product is widely used in non-standard waveform distortion sine wave real-time signal detection and monitoring.
