Product Introduction
DDS7766
1.Product Brief Introduction
1.The DDS7766 type single-phase electronic watt-hour meter adopt use LSI, the lorge scale integration typifying few periphery component, simply structure, high rellability, low power consumption, long life etc, is suitable for the single-phase AC active electric energy with rated frequency of 50 HZ. The performance is in conformity with the technical requirements for single-phase electric watt-hour meter stipulated in GB/T17215-2002 Class 1 anf 2 Static AC Active watt-hour meter standard.
2.Function and features
1 .Measure active electric energy, do not need to calibrate for long-term operation;
2.Adopt dedication meter age chip ADE7755;
3.Adopt lasted electricity dedication integrated circuit including digital multiplieroverseas, graetily improved dynamic working range of meter, making 10 multiple actual overload;
4.Have good mistake linearity in the range of 5% Imax;
5.Few periphery component, simple structure, low power consumption;
6.Adopt high relaiability and long life electronic component, so the meter assume feature of high relability and long life.
