DDS26D-SY01 Multi rate time-sharing anti-theft electricity meterDetailed product description：

summary:
The DDS26D-SY01 multi rate time-sharing anti-theft electricity meter is used to measure single-phase AC active energy with a rated frequency of 50/60Hz. All its performance meets all the technical requirements of the latest international standard IEC62052-11 IEC62053-21 IEC62056-21 for level 1 single-phase electricity meters.

Function:
1. It has a multi rate time-sharing energy metering function that can be programmed for up to 24 time periods and up to 4-8 rates, and measures active energy separately in each rate period. Users can program and set rate tables, backup rate tables, and automatic conversion times for backup rate tables as needed
2. Equipped with advanced anti-theft technology, it has the function of preventing electricity theft. For situations such as reverse or unbalanced current in the neutral and live lines of the energy meter, the energy meter can measure electricity normally and provide a warning for electricity theft or reverse usage. It can effectively prevent electricity theft behaviors such as reverse or one fire one place.
3. It has an event recording function that can record and read the last 50 power failure events and programming events (including the number and time of each event occurrence)
4. It has communication functions including infrared communication and RS-485 communication. Set or delete display items, clock settings, time period programming, meter reading and other functions of the electric energy meter through infrared and RS-485 communication interfaces.
5. The electric energy meter with automatic monthly data transfer function can automatically transfer the electricity consumption data of the previous month on the automatic transfer date and hour (which can be set), and can store the historical data of the previous 12 months. Data can be saved for 100 years after power failure.
6. The maximum current of a wide range energy meter can reach 100A, and the measurement range of 5-100A is 20 times that of a wide range energy meter that does not use range conversion
7. Equipped with maximum demand measurement and reset function
8. Equipped with backlight display and power outage display functions
9. Equipped with temperature detection and hardware self-test functions
10. The Persian calendar function can be selected to set the calendar to Persian calendar according to the user's needs
11. The function of switching between spring and summer time can be selected, and the automatic conversion function between spring and summer time can be set according to user needs
2. The functions of reverse power consumption event, lid opening detection event, and electricity theft event recording can be selected according to user needs, and the functions of reverse power consumption event, lid opening detection event, and electricity theft event recording can be set
13. The electric energy meter with optional reactive power metering function can set active and reactive power metering functions according to the user's needs
