Single-phase electric energy meter DDS858

DIN railpanel-mountwith LCD display

DDS858 single-phase electronic energy meter,is applied to House, Store electricity measurement. This meter adopts low-consumption circuit technical and SMT manufacture to measure the AC single-phase active power of rated voltage 220V,rated frequency is 50Hz/60Hz. This production conforms to standard of IEC61036:2000(IEC62053-21:2002). Function feature 1.Energy - measurement has high-accuracy and stable, no needs to adjust, can extend vérification cycle, and reduce the meter test and school. 2.Bidirectional - measurement function, accurate measurement of both positive and negative direction of the power. And in one direction the cumulative power, has anti-theft function. 3.The - photoelectric isolation technology is used to output electric energy puise signal, and can be used for error détection.(passive) 4.It adopts manganin diverter as current loop, to improve the meter overload capacity,and overload capacity up to more than 6 times. 5.It adopts large scale integrated circuit and SMT surface mount technology This product has advantages of wide load,high accuracy,high reliable,high sensitivity,small volume,low consumption,strong overload,convenient install.
