DDS7766 single phase electronic watt-hour meter adopt use LSI, the large scale integration typifying 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 requirements for single phase electric watt-hour meter stipulated in GB/T17215-2002 Class 1 and 2 Static AC Active watt-hour meter standard.

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, greatily improved dynamic working range of meter, making 10 multiple actual overload;

4. Have good mistake linearity in the range of 5%Ib~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.
