LU-192 Series Smart Digital Meters

I. Overview

    The LU-192D smart power monitor is a smart three-phase AC ammeter dedicated to measuring three-phase AC current, integrating automatic measurement, digital tube display 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 and reduces human error. With compact structure, advanced circuitry and powerful measurement functions, it is a revolutionary design compared with traditional instruments.

    The LU-192D smart power monitor can be widely used in electrical installations, automatic control and dispatching systems in industries and sectors such as electric power, post and telecommunications, petrochemicals, coal, metallurgy, railways, municipal engineering and intelligent buildings.
