DDS122 single-phase electronic energy meterDetailed product description：

summary:
The DDS122 fully electronic single-phase active energy meter is designed and manufactured using ultra-low power large-scale integrated circuits and SMT technology. It is equipped with a high reliability mechanical meter to accumulate and indicate electrical energy, and is used to measure AC active energy in single-phase power grids with a rated frequency of 50HZ. Complies with all technical requirements of Class 1.0 three-phase energy meters in IEC1036 and GB-T17215.

Main functional features:
1. High precision, high overload, high reliability, low power consumption, wide load capacity.
2. Bidirectional metering function, accurately measuring active power in both positive and negative directions, accumulating electrical energy in the same direction, with anti-theft function.
3. Equipped with a photoelectric coupling pulse interface.
