Description
With high accuracy, good sensitivity and excellent resistance to vibrations,Sanda's digital three phase multifutional electric meter can be used as electricity parameters indicator to replace analog pointer meter . Also it may be as the front-end collection components of automation system. And also it may be acted as continuous measurement and monitoring unit of power distribution system. The main application fields are following:
▪ Factory dynamic system automation and load control;
▪ SCADA, DCS, EMS integration manufacturer;
▪ Substation general automation;
▪ Power plant Electric DAS;
▪ Post Office Power Supply Systems, Intelligent Building
▪ Energy Management System
And man-machine interface let the meter more simple and better to understand. Voltage,current,,power,power factor, frequency,electric energy can be displayed in real-time on the panel. Communication parameters and analog parameters, can be set through the panel. Data are stored in nonvolatile memory and would not be lost even on power-off. And the data can be reserved more than 10 years.
