LU-191 Series Smart Power Transducers

I. Overview

    The LU-191 smart power transducer is an intelligent power parameter acquisition module that can measure three-phase current, voltage signals, active power, reactive power, power factor, apparent power, frequency, energy and other parameters. To meet the requirements of network communication and intelligent integrated distribution monitoring, the following options are available: RS-485 communication interface, RS-232 communication interface and RS232 printing. 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 watt-hour meters, digital display meters and data acquisition units, and is an ideal product for building electrical automation systems. It features compact structure, small size, light weight and great ease of use.

    The LU-191 smart power transducer can be widely used in modern power supply and distribution systems such as electric power, post and telecommunications, petrochemicals, coal, metallurgy, railways, municipal engineering, industrial and mining enterprises, civil buildings and substations as a high-performance, low-cost automation instrument.
