Multifunction Power Meter is for power systems, industrial and mining enterprises, public facilities, intelligent building power monitoring, intelligent control, metering applications designed to assess accuracy, high reliability, high cost of intelligent instrumentation. This series of instruments using high-precision dedicated AD chip MCU design and high reliability can be measured three-phase grid all the power parameters such as three-phase voltage, phase current, active power, reactive power, power factor, line frequency, two-way energy metering and THD, etc., with standard power pulse and RS485 communication interface, a variety of optional expansion modules (switch input and output, analog output, multi-rate electric energy statistics, harmonic analysis, etc.). The series has a very high price, it can directly replace conventional power transmitter, measuring instruments, electrical measuring instruments and related auxiliary unit. As an advanced intelligent network front-end digital capture devices, Multifunction Power Meter has been widely used in various control systems, SCADA systems and energy management systems, substation automation, distribution automation, residential electricity monitoring, industrial automation , smart buildings, smart power distribution panel, switch cabinet, with easy installation, wiring is simple, easy maintenance, engineering, field programmable set of input parameters to complete the trade without PLC, industrial computer network communications software. 18879978399
