General
    DSSD63/DTSD63 Three phase Electronic Multi function Energy Meter(active bidirection reactive four-quadrant) are high-tech and intellectualized instrument with integration of special techniques such as the special integrated circuit for electric-energy meter, nonvol-atile memory for keeping information forever, standard RS485 communication interface, infrared communication, large-frame super-twist wide-temperature LCD; they also use the new SMT electronic connection technology, and are upgrade-type electric-energy meters and elaborately manufactured according to IEC standards.
    These products combine many functions together, and realize the active bi-direction and sine-type reactive four-quadrant multi-tariff measuring of electric energy, dem-and measuring, measuring of power factor, and multi-tariff prepayment; and can display and tele-transmit the average load power including voltage, current and power, etc. They can also realize all functions of record, alarm and display of voltage loss and current loss, and can effectively pilfer proof.
Main functions
●Realize GSM or GPRS meter-reading in a for disturce;
●Measuring the bi-directional active and four-quadrant reactive electric energy;
●Measuring the bi-directional active and four phase reactive maximum demand;
●Storing the electric energy and maximum demand in six meter-reading cycles;
●Four kinds of tariff, which can switch 12 times wveryday, and can set the offdays and holidays;
●Six sets of period table, and each year can be divided into four season periods;
●Active without power reactive pulse output, passive active forward and second impulse output, and the pulse width can be programmed;
●Voltage loss and current loss timing and display;
●Measuring voltage, current, power and power factor;
●Alarm at exceeding demand power;
●Setting circulating display and power failure display;
●Realizing programming and control display with key-press and remote controller;
●Upper computer can read the real-time active and reactive power of this meter, and generate the load curve in random time density, so as to perform more resonable power-utilization management.
