LCD multi-function power meter
Multifunctional power meter, embedded installation, light and convenient, easy to install, measuring three-phase current, three-phase voltage, electric energy, power, power factor, 485 communication, etc.
The power meter is a multifunctional intelligent power meter with programmable measurement, display, RS485 digital communication and electric energy pulse output. It can complete three-phase electric parameter measurement (three-phase voltage, three-phase current, active power, reactive power, apparent power, power factor, frequency, etc.), harmonic measurement, power grid quality analysis (voltage crest factor, current K factor, telephone waveform factor, voltage and current unbalance, voltage and current sequence quantity, etc.), four-quadrant electric energy metering, multi-rate electric energy metering, maximum demand recording, SOE event recording, data display, collection and transmission. It can be widely used in substation automation, distribution automation, intelligent buildings, and internal enterprise electric energy measurement, management, and assessment. The measurement accuracy is 0.5 level, and it realizes LCD field display and remote RS-485 digital interface communication, using standard MODBUS-RTU communication protocol.
The network multifunctional power meter has a variety of extended functions for selection: 4-way analog quantity transmission output, 4-way relay output (can be used as local electric parameter alarm or remote control output), and 4-way switch quantity input.
