  • This product is an intelligent isolation transducer of electrical parameter acquisition and transmission. It can measure the full-parameter of three-phase four-wire AC loop. Using high-precision 24-bit dedicated AD chip, the ratio dynamic range can be up to 5000: 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
