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
