      Overview:

      DDS949 single-phase electronic anti-theft electric energy meter is used to measure single-phase 50-60Hz AC active energy, suitable for home and residential users. It features high measurement accuracy, long-term stable work, low power consumption, and provides anti-theft functions such as removing neutral and reverse. It complies with 1EC 62053-21/iEC62056-21.


      The main function:

      1. Double loop energy measurement

      2. Forward/reverse energy measurement

      3. Reverse electric energy meter

      4. Maximum demand measurement (optional)

      5. Anti-theft: reverse phase, remove neutral

      6. Voltage interference (resistance, capacitance and thyristor interference)

      7. Magnetic field detection

      8. Abnormal event display

      9. Power failure low power consumption mode
