  • This product is a true RMS measurement 2 phase AC voltage isolation transducer. Using the principle of electromagnetic isolation to sample the two-way AC voltage, isolated output a variety of standard signals such as 0 ~ 5V, 0 ~ 20mA or 4 ~ 20Ma after the true RMS conversion, its input and output are electrical isolation. There is a complete linear relationship between the output signal and the input signal. Products have an advantage of good accuracy, high isolation pressure, low temperature drift, small size, easy installation, etc., in line with international standards, it can be widely used in AC voltage signal real-time detection or monitoring, communications, electricity, railways, industrial control and other fields.
