LU-DP Series Smart Digital Meters

I. Overview

    The LU-DP4IW smart power monitor is an intelligent monitoring instrument integrating programmable functions, automatic measurement, digital tube display, energy accumulation 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. It can fully replace instruments such as power transducers, watt-hour meters, digital display meters and data acquisition units, and is an ideal product for building electrical automation systems. With its compact structure, advanced circuitry and powerful measurement functions, it is a revolutionary design compared with traditional instruments. The display can be switched between single-phase current and energy values.

     The LU-DP4IW 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.
