LU-193/190 Series Multi-function Meters

I. Overview

    The LU-190 series intelligent power monitor is an intelligent three-phase comprehensive power parameter monitoring instrument integrating programmable functions, automated measurement, LCD display, energy accumulation and digital communication. It converts three-phase AC electrical quantities into standardized digital values according to a linear relationship. Combining digitalization, intelligence and networking, it automates the measurement process and data analysis and processing, reduces human error, and can fully replace power transmitters, watt-hour meters, digital display meters, data acquisition units and other instruments. It is an ideal product for building electrification systems; with its compact structure, advanced circuitry and powerful measurement functions, it is a revolutionary design compared with traditional meters.

    The LU-190 series intelligent power monitor can be widely used in electrical installations, automatic control and dispatching systems in industries and sectors such as power, post and telecommunications, petroleum, coal, metallurgy, railways, municipal administration and intelligent buildings.
