LU-192 Series Smart Digital Meters

I. Overview

The LU-192U smart power monitor is a smart three-phase AC voltmeter dedicated to measuring three-phase AC voltage, integrating automatic measurement, digital tube display and digital communication into one unit. It converts three-phase AC electrical quantities into standardized digital quantities according to a linear relationship. Combining digitization, intelligence and networking, it makes the measurement process and data analysis and processing automatic and reduces human errors. With its compact structure, advanced circuitry and powerful measurement functions, it is a revolutionary design compared with traditional instruments.

The LU-192U 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.
