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