Product Name: Single-Phase Static Multi-Tariff MeterModel Number: DDSF200-EPlace of Origin: ChinaGeneral introduction: adopting the latest special energy measuring chips developed by ADI Company and using - sampling conversion technology, the meters achieve high accurate, high overloading single-phase active Multi-tariff electric energy measurement. DDSF200-E main functions cover: time-sharing electric energy measurement, mass electric energy storage, power turn-off, energy supply recovery, electric energy pulse output, infrared communication , RS485 communication, and so on. Its an indispensable high-tech product for electric energy department to realize the time-sharing residential electric cost and modern electric energy measurement management.Main characteristics:1) Adopting ADI s special electric energy measuring chip, they areremarkable in highaccuracy, high overload and good linearity2) When main power is shut off,the data will be saved automatically to ensure noenergy and relevant data will lose3) Adopting watt-hour meter and LED alternate displaying mode to display electricenergy data and current operating mode of watt-hour meter, such as, current ratestate and communication mode4) Random reading function. They are able to store electric quantity of integral point inthe latest two months, to read electricity consumption information at any moment,and to calibrate the clock automatically after reading5) Time zone can be divided into 2 periods: heating period and non-heating period6) Heating period can be divided into 2 periods of time: smooth period and troughperiod7) Time and calendar are built in them, so that the date can automatically switchbetween leap year and non-leap year8) The automatically switch by RS-485 and infrared communication, makes the settingand reading meter become more convenient and accurate9) Authorization setting, software password, and high confidentiality10) With MIS download command, the meter can automatical control power turn-off ofthe usersTechnical index:1) Accuracy: class 1.02) Reference voltage: 220V AC3) Current specification: 5(30)A; 10(60)A; 20(80)A4) Standard Reference frequency: 50Hz5) Operating voltage range: 154-264V AC6) Power consumption of voltage circuit:7) Power consumption of current circuit:8) Starting current:9) Shunt running: no pulse output10) Operation temperature range: -25 ~ +55oC11) Storage temperature range: -25 ~ +70oC12) Relative humidity of operating mode: annual average relative humidityFunctions:1) Measurement function2) Rate and period of time3) Communication function4) Setting authorization function (Authorization function consists of two modes: thepassword verification and short circuit wire jumper)5) Display function6) Mass storage function7) Power turn-on and power turn-off function
