Application
DDS1777 single-phase watt-hours electronic type using special large-scale integrated circuits,which is few periphery component, simply structure, high reliability, low power consumption,long life etc ,is suitable for the single-phase AC active electric energy with rated frequency of 50Hz. The performance is in conformity with the technical requir ements for single-phase electric watt-hour meter stipulated in GB/T17215.321-2008Class 1 and 2Static AC Active watt-hour meter standardand International Standard IEC62052-11:2003.
Besides Measure active electric energy, do not need to calibrate for long-term operation;
Adopt dedication meter age chip ADE7755;
Adopt lasted electricity dedication integrated circuit including digital multiplier overseas,greatily improved dynamic working range of meter, making 10 multiple actual overload;
Have good mistake linearity in the range of 5%Ib~Imax;
Few periphery component,simple structure,low power consumption;
Adopt high relaiability and long life electronic component,so the meter assume featrue of high relability and long life.
Watt-hour meter housing to change according to customer requirements, full range.
