Brief Introduction
LU-190 intelligent electric power monitor is for surveying of three-phase synthesis electric power parameters, it has many functions such as the programmable, automatic survey, LCD display, electrical energy accumulates, digital communication and so on. It can transform the three-phase ac electric value into the standardized digit value according to the linear relations. It has the characteristic of digitization, intellectualization & network, to make the survey process and the data analysis processing realizing automation, reduces the artificial fault, can comprehensively substitute electric value transformer, the electrician meter, the digital display meter, data acquisition and so on meters, it is an ideal product for the electricity automated system. Its structure compact, circuit advanced & survey function formidable, is a revolutionary design to the traditional meter.
LU-190 is widely used to the field of electric power, Post and telecommunication, petroleum, coal, metallurgy, railroad, municipal administration, intelligent building, and the electric equipment of department, automatic controlling and dispatching systems.
