AMR System Smart Electric Meters for Domestic Usage with Prepaid Function DLMS/COSEM
DDZY150 single phase local fee control smart meter is a intelligent electricity metering product, which suit for measuring 220V/50Hz single phase active AC power. It has independent optical and RS485 interface, and also with standard interface of carrier communication module, which can work with carrier communication module from different suppliers. It can support for fee control function. With advantages of high reliable, high accuracy, long life, wide range and etc, it can widely used in city, country and enterprises where need to measure single phase AC power.
Standard: IEC 62053-21 Electricity metering equipment (a.c.) –Particular requirements –
Measured AC voltage and current have been sampled and transported to professional metering chip, after digital processing, they have been changed to the pulse signal, which in direct proportion to active power, and then sent to microprocessor. Microprocessor would accumulate the pulse signal according to the tariff, then get total power and tariff power and put them in register. At the same time, the microprocessor finishes the function of display and changeover with external messages. Please take attention to the Figure 1
|Connection Mode||Accuracy||Rated Voltage V||Rated Current A||Pulse Constant|
|Through Mutual Inductor||1.0/2.0||220||6||12000|
Remarks: Special pulse constant can be customized as inquire.
1. Product's Type—Remote, Remote Carrier, Local, Local Carrier.
2. Electric Power Measurement—Positive active power, reverse active power can be measured, and according to which setting for active group. For active power, it can accumulate and storage total, top, peak, flat, valley power. It can storage and display total power and power for each tariff for last 12 months.
3. Multi Tariff—With 2 sets of tariff, which can changeover automatically on appoint time. Each tariff can support for 4 rates. It can set 14 time zones in a year, and program at most 14 periods in 24 hours. The minimum time interval is 15 minutes for periods, which can be set over 0:00am.
4. Ladder Billing—With function for ladder billing, two programs of electrovalence, which can be changed over automatically at appoint time or reach appoint electricity consumption.
5. Event Log—With function for logging events such as clear, program, timing, power down, switch out, switch on, open meter cover and etc.
6. Electricity Freezing—With multi freezing ways of instantaneous freezing, timing freezing, day freezing, appoint freezing, on hour freezing and etc.
7. Load Profile—It can profile kinds of operation for query analysis.
8. Measure Function—Real time measuring and displaying current voltage, current (including zero line current), power, power factor and gird frequency, and it can also display the operating parameter such as direction of power.
9. Demand Operating—Handle parameter setting, prepaid electricity charge, information write back, switch out and switch on demand to the meter through solidity or virtual medium.
10. State Indicator—LED indicators for pulse, warn, switch out, and error code would be displayed on LCD, which can help to understand the working state for meter.
