Detailed Product Description

  Product Brief Introduction     DSSF8888/DTSF8888 three-phase electronic multi-rate watt-hour meter can metering active forward and reverse direction accurately, own the function of recording the max demand ,measure and process the voltage, current ,power etc parameter all the time. Own the function of time-sharing control, reading automatic, data storage of electric quantity and demand quantity ,the record of current operate state and event record etc.which is a ideal intelligent instrument of realizing time-sharing metering and checking working. This kwh adopt large scream LCD to display with the port of remote infrared, RS485 etc.   Function and  features   1Each 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    2All the consumption date can be reserved for 12 months    3The meter adopts the advanced energy measuring chips,  high capability CPU and RTC clock chips    4Recording the active electric quantity and the electric quantity under every rate, and reserved it    5High accuracy, sensitivity and reliability, wide overload endurance, low power consumption and light in weight    6Auto accumulate and recording the working time of the battery    7Display the present time, rate, total electric power and every rate electric power    8Communicate Agreement accord with DL/T645-1997    9It has pulse output communication, pulse width:80ms±20ms  10It adopts the password and program switch protection, recording the latest program time and degree  11It can setup the meter number, bureau numbertime-periodratedatetime, meter reading time, password and the initial electric power  12Can move through some form cover wheel show button look over the electric consumption parameter that users select  13.  Own the function of measuring the max demand quantity    Specification and Technical Data     1Rated Current(A)3×1.5(6),3×5(20),3×10(40),3×15(60),3×30(80),3×30(100)    2Rated Voltage(V)Three-phase four-wire 3×220/380V or 3×57.7/100V                            Three-phase Three-wire 3×100V or 3×380V    3Rated Frequency(Hz)5060    4Accuracy classclass 1.0, class 2.0    5Clock error0.5sec/per day (Reference temperature)                       1.0sec/per day (Operating time is supported by lithium battery)    6Batteryimported environmental protection lithium battery Voltage:3.0 or 3.6             Capacitance≥1000mAh
