EV/DV300 series power meter is designed for three phase electrical parameter measurement by using of latest microprocessor and digital signal process technology. It can True-RMS measure Voltage, Current, Power, Reactive Power, Power Factor, Frequency and Energy. The meter can be well used in high harmonic environment especially in middle and low voltage power system, electric apparatus, power system automation and factory automation. All the measuring electrical data are available via digital RS485 communication port running ModbusTM Protocol. The meter also got some flexible I/O ports that made the metering, monitoring, remote controlling and Analog output in one unit possible. This can save large cost for user in setting up electric power automation system.
EV/DV 300 series meter can be used to replace analog meter, panel meter, transducer and small RTU in power distribution or power automation system. As it adopted true-RMS measuring method, the EV/DV 300 series are competent for meauring voltage and current in high distortion nonlinear load system, such as VVVF, Electric Ballast, Computer etc.
