CPU Card Smart Electric Meters Single Phase Multi Function Smart Meter for AMR System
The DDZY150 type electronic single phase multi-rate watt-hour meter adopts advanced energy metering chip, combined with mature multi-rate technology by using digital sampling processing and SMT technology. We develop this international standard meter according to residents’ actual power consumption. It offers functions as time measurement, automatically archived data set, hand-held terminal or PC programming and meter reading, also the LCD display etc..
The meter has two sets of fee charged. It can be transferred automatically as arranged; each set supports no less than four rates. It offers positive and reverse active energy metering, time measurement, separately memorizing electricity energy for the total, sharp, peak, level and valley period.
2. Remote Fee Control
It finished parameter setting and remote purchasing through RS485, carrier and other virtual medium..
2.1 Remote Fee Control Electricity Meter
The calculative process for electricity is finished in remote system, there is no relative information such as electricity fee have been stored or displayed in meter. Meter has to pass strict password authentication and safe certification since getting remote commands such as switch out, switch on, ESAM data reading.
2.2 Encryption required for safe certification
To make sure the reliable and safe data transportation, the commands from meter through solid or virtual medium have to pass strict password authentication or safe certification such as ESAM module.
3. Measuring and Monitoring
It can measure and monitor operating parameter such as voltage, current (including zero line current), power, power factor and etc. The error would not exceed ±1%
4. Event Log
--Alarm Red, it is off in normal condition, and would be on when alarming
--Trip Yellow, it is off in normal condition, and would be on when load switch disconnect.
When the following faults or alarm appear, LCD would stop on the certain code and backlight keep on.
Err-01 Control Loop Error
Err-02 ESAM Error
Err-04 Low Voltage for Clock Battery
Err-08 Clock Error
Err-10 Error for Certification
Err-16 Error for Key Correction
Build in clock circuit with temperature compensation function, the calendar, timing, leap year can be changed over automatically. The output frequency for inner clock terminal is 1Hz. Between -25℃ to +60℃, clock accuracy is no more than ±1 s/d; Under reference temperature 23℃, clock accuracy is no more than ±0.5 s/d.
The accepted time broadcasting is no more than 5 min. No need to match with programming switch and communication password when time broadcasting. It can be set according to the inquire, and it avoid from handling in 5 min at the time when freezing or data storing.
9. Pulse Output
Meter has function for LED pulse and electrical pulse output which comes direct ratio with measuring energy. Optical test output device should comply gb/t17215.211-2006, electricity test output device should comply GB/T15284-2002. It has signal output terminal for clock, and the output frequency is 1Hz
10. Load Switch
External load switch, there is a group of switch signal for meter output. Volume of switch point is AC 220V/2A. Under normal condition, switch signal for output should keep switch on of load switch, allow for power on; When reach certain condition, switch signal for output should drive operation for external load switch, power off.

＊ Use only isolated tools.
＊ Do not connect the meter to a 3 phase - 415V AC - network.
＊ Place the meter only in dry surroundings.
＊ Make sure the used wires are suitable for the max current the meter can measure.
＊ Make sure the AC wires are installed correctly before activating the current/voltage.
＊ Do not touch the meter connecting clamps directly with your bare hands, with metal, blank wire or other material as you will have the chance of an electricity shock and a possible chance for health damage.
＊ Make sure the protection cover is placed after installation and has been sealed.
＊ Installation, maintenance and repair should only be done by a certified electrician.
