Introduction
The DDS794 TYPE SINGLE-phase electronic energy meter adopts specialized LSI, the device typifies few periphery component, simple structure, high reliability, lower power consumption, long life, etc. It is suitable for the single-phase requirements for sing-phase electronic watt-hour meter stipulated in GB/T 17215.321-2008 Class 1 and 2 Static AC active kwh energy meter standard.

Functions and features
Measure active electric energy, do not need calibrate for long-term operation;
Adopt dedication meter age chip ADE7755 for energy meter;
Adopt lasted electricity dedication integrated circuit, greatly improve dynamic working range of meter,
Making 5 multiple actual overload;

Have good mistake linearity in the range of 5% lb~max;
Few periphery component, simple structure, low power consumption;
Adopt high reliability and long life electronic component, so the meter assume feature of high reliability and long life.
