LU-192 Series Smart Digital Meters

I. Overview

    The LU-192H full-function smart power monitor is a smart three-phase comprehensive electrical parameter monitoring instrument integrating programmable functions, automatic measurement, digital tube display, energy accumulation and digital communication. It converts three-phase AC electrical quantities into standardized digital values in a linear relationship. Combining digital, intelligent and networked technologies, it automates the measurement process and data analysis, reduces human error, and can fully replace power transmitters, electricity meters, digital display meters, data acquisition units and other instruments, making it an ideal product for building electrical automation systems. With compact structure, advanced circuitry and powerful measurement functions, it is a revolutionary design compared with traditional instruments.

    The LU-192H full-function smart power monitor can be widely used in electrical installations, automatic control and dispatching systems in industries and departments such as power, posts and telecommunications, petrochemicals, coal, metallurgy, railways, municipal administration and intelligent buildings.
