3-phase 3-wire AC Voltage Digital Transducer
This product is a 3-phase 3-wire AC voltage acquisition and measurement digital isolation transducer. The two-wattmeter method is used to measure the voltage of 3-phase loop. Using high-precision 24-bit dedicated AD chip, the ratio dynamic range can be up to 1000: 1. Using true RMS measurement, which is with high accuracy, good stability and high communication speed, the completely isolated processing technology is with anti-interference ability. Measurement of electrical parameters through the RS-485 digital interface output to achieve long-distance transmission, the product MODBUS protocol is complete compatible with a variety of configuration software or PLC equipment MODBUS (RTU) protocol. It can be applied to power, room monitoring, industrial measurement and other fields.
