DSZ1122 Level 1 Three Phase Intelligent 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 single-phase residential energy metering in smart grids. Main functions and features: 1. Electricity metering: It can measure phase separated and total active and reactive bidirectional time-sharing electricity; Measurable reactive energy in four quadrants; Measurable combined active and reactive electrical energy, with characteristic words for combined active and reactive power that can be set. 2. Instantaneous data monitoring: can monitor real-time values of voltage and current in each phase; It can monitor instantaneous quantities such as total and phase active power, reactive power, apparent power, power factor, phase angle, etc. 3. Time of use metering: It can accumulate and store total, peak, off peak, off peak, and off peak electrical energy according to the corresponding time period, and can store the total electrical energy and various rate electrical energy for the previous 12 settlement cycles. 4. 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. 5. Freezing data function: It has timed, instantaneous, agreed, hourly, and daily freezing functions, and the freezing data mode can be set. 6. Event recording function: It has event recording functions such as power failure, programming, meter reset, event reset, timing, opening the meter cover, starting button, full voltage loss, voltage loss, phase failure, current loss, power reversal, and demand exceeding. This function can effectively prevent users from illegally stealing electricity. 7. Communication function: It has communication interfaces such as infrared communication and RS485 for exchanging data with the outside world. 8. Demand measurement: It has the measurement function of six basic demand types: positive active power, negative active power, and reactive power in four quadrants, and is unified according to the settlement cycle .....
