This device is a 3-phase AC voltage isolation transducer. Using the principle of electromagnetic isolation to measure the three-phase AC voltage signal, isolated and linearly output a variety of selectable standard signals. It can be widely used in AC voltage signal real-time detection and monitoring, communications, electricity, railways, industrial control and other fields.
