DSSD22 Level 1 Three Phase Three Wire Multifunctional Energy Meter

Main features: Three phase smart energy meters are designed and manufactured using large-scale integrated circuits, digital sampling technology, and communication functions according to the requirements of "informationization, automation, and interactivity" construction of smart grids. They are mainly used for measuring the electrical energy of three-phase residential households in smart grids. Main functions and features: 1. It has the function of measuring positive and negative active power and combined active power, and the characteristic words of combined active power can be set; 2. It has a time-sharing metering function, which can accumulate and store the total, peak, off peak, flat, and valley electricity energy according to the corresponding time period. It can store the total electricity energy and electricity energy at various rates for 12 settlement cycles; 3. Time slot rate function: It has two sets of rate time zones and time slot tables, which can be automatically converted at the agreed time; 4. It has functions of timed, instantaneous, agreed upon, hourly, and daily freezing, and the freezing data mode can be set; 5. It has real-time parameter measurement functions such as voltage, current, power, power factor, and grid frequency; 6. Capable of recording events such as power failure, event reset, meter reset, timing, programming, and cover opening; 7. Communication interfaces with infrared communication, RS485, etc. for exchanging data with the outside world; 8. Adopting fully automatic software calibration technology, the calibration is simple, fast, and accurate; 9. Adopting an integrated design of cover and lid, the appearance is novel, beautiful and practical.
