    DDSYF668 Single-phase Electronic Multi-rate and Prepayment Watt-hour meter

    Summarize

    DDSYF668 Single-Phase Electronic Multi-rate & Prepayment Watt-hour Meter is a new generation electric energy measuring meter made by advanced solid integration technology and SMT production process . Electricity cost is prepaid before the electricity can be used, and effectively avoid difficulties in receiving electricity cost and meter reading, and using computer system processed management and supervises and control in electricity cost of the whole intelligence. It is used CPU card (intelligent card), has powerful function do not deencryption, has the virtue of the small volume, light in weight, high reliability and etc.

    All watt-hour meter with IC card has two kinds of display series with figures tube and LCD, with or without counting meter, has single phase directly connected and single phase connected with mutual inductance. With different current specification, and according to requirements of users, the products is made up 1,4 connection or 1,2 connection.

    Applicable scope

    The kind of meters is applicable to electric energy measurement and management. Prepayment , employing CPU card technology takes place conventional manpower meter reading. It becomes an ideal product for electric supplier in cities to realize automatic billing management , load management, improving efficiency of power network , intelligent adjusting electrovalence and to resolve problems like owing electric power charges.

    Characteristic

    1.Adopted ADE7755 chip, measurement is precision, to reach accuracy of class 1.

    2.The intelligent card is realized safety with encrypted key authentication, so safety grade is tiptop. None but intelligent card is realized safety mechanism of the password, which has something to do with the electricity sales management department and which has nothing to do with manufactory.

    3.The strict partitioning producing status, installing status and using status.

    4.Possessing precautions against of the illegal attack. for example IC card port.

    5.The different electrovalence correspond to the different load, the meter realized intelligence adjusting electricity of user.

    6.Supervision of each other: electrovalence, purchase electricity cost, alarm ,overdraft, capacity and coemption can be set up by user card, the time zone, period of time can be set up by user's management card. RS-485 or Infrared can be used setup of time zone, period of time , time and remote meter reading.

    7.record recent 32 month's information of electric consumption including total and different tariffs.

    8.Bi-directional measurement: Measurement can still be performed accurately even if input and output wires of the meter are connected reversely.

    9.Data in storage can be hold over ten years after power lost

    10.Working life : 20 years.

    Basic function

    1.Function of real time clock : The meter provides calendar and clock. And leap year is adjusted automatically.

    2.Per year can be divide into four time zone ,the time zone can be divide into ten period of time with four different tariffs.

    3.Electricity energy measurement: time-sharing measuring electric consumption ,time-sharing valuation and educing remaining money.

    4.Hoarding the most money。

    5.3-level alarm, automatic switch off and switch on, overdraft of the most money.

    6.Load setup and overload indication.

    7.Alarm for failure, the failure of relay can be detected and indicated.

    8.Revolved displaying after key is pressed.

    9.Indication after the power is turned on.

    10.Infrared communication: through a hand held unit and Infrared interface, you can read data or program parameters of the meter.

    11.RS-485 standard interface: RS-485 communication interface is provided inside the meter, which makes it real timing reading and setting for automatic management.

    12.Impulse and rate indication: the meter has impulse indication function and current rate indication function.

    13.Event record function: themeter has power cut inspection function, and can record the last three power cut date and time, respectively record time setting (including broadcast timing), electricity quantity reset time and data before setting, and data is the latest three data.

    14.Power theft inspection and negative power theft function: themeter can inspect bridge connection power theft, and keep record. When incoming wire and outgoing wire is connected negatively, the metering module can still meter normally.

    15.Self-diagnosis: meter automatic detection control model, data memory and other units can work normally or not, and automatically record fault condition and occurrence time when fault is detected, and inform the central control system.

    16.Remote communication: the meter can communicate with the meter reading device via wireless or power wire carrier wave.

    Operating parameter of battery

    1.The battery capacity ≥1000mAh.

    2.The battery working life ≥10 years (natural discharge)

    3.Clock retention time after power off ≥10 years (using battery)

    4.Clock retention time of changing battery in the case of power off ≥10min.

    5.Battery consumption after power off ≤10uA.

    Pulse output port:

    Meter is equipped with electric isolated pulse output port for calibration.

    Configuration

    Using IC card as media, the meter is a part of electric power consumption management system. The system also included IC card writer/reader, electrical power marketing software, and computer network.

    System extension

    Be considered as an important part of future automated management of electric power network.
