three-phase multi-rate smart meter

smart meter,remote meter, meter reading Product Brief Introduction Three-phase electronic multi-ratesmart meter adopts the advanced special energy measuring chips and the multi-rate technology. Using the digital sampling process technology and SMT technology. The product is designed and produced according to the practical situation of the dweller,all the elements inside the meter have the feature of long-life, high-reliance Function and features 1 Each of four periods has different rates(point period, peak period, smooth period and trough period). Every period of time can be programmed into 12 periods of time and the minimum time interval is five minutes 2 All the consumption date can be reserved for 12 months 3 The meter adopts the advanced energy measuring chips and high capability CPU and RTC clock chips 4 Recording the active electric quantity and the electric quantity under every rate, and reserved it 5 High accuracy, sensitivity and reliability, wide overload endurance, low power consumption and light in weight 6 Auto accumulate and recording the working time of the battery 7 Display the present time, rate, total electric power and every rate electric power 8 Communicate Agreement accord with DL/T645-1997 9 It has pulse output communication, pulse width:80ms±20ms10 It adopts the password and program switch protection, recording the latest program time and degree 11 It can setup the meter number, bureau number,time-period,rate,date,time, meter reading time, password and the initial electric power 12 Can move through some form cover wheel show button look over the electric consumption parameter that users select, see all project contents tabulate in very selected electric consumption parameter Specification and Technical Data 1 Rated Current(A)3×1.5(6),3×5(20),3×10(40),3×15(60),3×30(80),3×30(100) 2 Rated Voltage(V)Three-phase four-wire 3×220/380V or 3×57.7/100V, Three-phase Three-wire 3×100V or 3×380V 3 Rated Frequency(Hz)5060 4 Accuracy classclass 1.0, class 2.0 5 Clock error≤0.5sec/ per day ≤0.1sec/perday 6 BatteryImported lithium battery Voltage3.0or3.6 Capacitance≥1000mAh
