3-phase 4-wire AC multi-parameter digital transducer
HOME > Multi-parameter > AC Multi-parameter Digital Transducer
This product is a 3-phase power integrated measurement of 3-phase 3 wire digital isolation transducer. The two- table method is used to measure the full-parameter of three - phase three - wire AC loop. Using high-precision 24-bit dedicated AD chip, the ratio dynamic range can be up to 1000: 1, the measurement parameters are voltage, current, frequency, active power, reactive power, power factor, total accumulative energy and other electrical parameters 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.
