Product Overview
Description
OEM 380V Voltage Current Power Frequency Combination Digital Panel Meter
The multi-function monitoring instrument is a performance monitoring instrument. It has the functions of high-precision real-time measurement of power parameters, harmonic measurement, forward and reverse active/reactive energy measurement, time-of-use energy measurement, time-of-use energy timing meter reading, power quality analysis, real-time waveform display, event recording, demand and other functions. And equipped with a wealth of input and output interfaces can be used for monitoring and control of field equipment status, It also integrates the RS-485 communication interface, which can be integrated with various intelligent power distribution systems and energy management systems to share rich monitoring data and power quality data.
The multi-function monitoring instrument has a very high cost performance and can directly replace conventional power transmitters, measuring instruments, electric energy meters and related auxiliary units. The application fields are very wide, such as energy management systems, power monitoring systems, industrial and mining enterprises, public facilities, intelligent buildings and switch cabinets and other power distribution network systems.
