LU-193 Multi-Function Power Meter

详情

1. Brief introduction
LU***3 intelligent multi-function power meter is for measuring of three-phase power parameters, it has many functions, such as: programming, automatic measuring, Stroke segment LCD display, multi-rate energy accumulation, energy demand measuring, digital communication and so on. It can transform three-phase AC value into standardized digit value according to the linear relation. It has characteristic of digitization, intelligentization & networking, which makes the measuring process and the data analysis processing realizing automation, reduces human error. The power meter can comprehensively substitute power transducer, KWh meter, digital display meter, data acquisition unit and so on; it is an ideal product for the electric automatic system. It has compact structure, advanced circuit & powerful measuring function; it is a revolutionary design to the traditional meters.
LU***2 intelligent power meter is widely used in fields of electric device, automation control system and dispatching system, in industries of Power, Post and Telecommunication, Petroleum, Coal, Metallurgy, Railroad, Municipal administration, intelligent building…
