Single Phase Current Measurement Power Analyzer Meter With Multifunction Network Instrument
Summarize
Multifunctional power meter can measure the power parameters used in three-phase power system with high precision: three-phase voltage, current, active power, reactive power, power factor, grid frequency, active power, reactive power, and with communication interface and power pulse output function. MODBUS-RTU communication protocol is used to realize LED field display and remote RS-485 digital communication. It has the characteristics of easy connection and installation, simple wiring, convenient maintenance, small engineering amount, field programmable setting input parameters, etc., and can complete the networking communication with different PLC and industrial control computers in the industry.
