Single Phase Two Wires Lora Smart Meter for Residential with Lora-RF Module

 

Descprition:

The Meter is used for a wide rang of prepaid applications. It combines latest 3DES security encryption technology and modular communication unit. The meter is allowing a basic current of 5 Amp while retaining a maximum current of 80 Amp and extended AMR/AMI functional features. It is a compact design in a BS8565 standard housing and maintains the rugged RF immunity withstand of 30V/m and IP54 rating, allowing it to operate in harsh environments. It transmits data to the appropriate gateway through LoRaWAN wireless ad hoc networks. It has high precision, low power consumption, good stability, and can be widely used in city, country or school and any enterprises.

≤ ±1.0s/Day (from -25 to +60 centigrade)

Data Storage Period ≥ 10 years
Digital Display 6+2 LCD

 

Features:

1. Metering

1.1 Measuring for positive and reverse active power, storage the data, and according to which setting active group.

1.2 Multi tariff. For active power, it can accumulate and storage total, top, peak, flat, valley power according to certain period.

1.3 It can storage total power and power for each tariff for last 12 months. The boundary is 24:00pm of end of month, or on the hour from 1st to 28th for every month.

 

2. Remote Fee Control
It finished parameter setting and remote purchasing through LoRa.

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.

 

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

4.1 Permanent record the time when reset happened, and also the data on that time.

4.2 Recording total times for programming, the time for last 10 programming and also operation code and data identification for programming.

4.3 Recording total times for timing (not including time broadcasting), the time for last 10 timing and also operation code.

4.4 Recording total times for power down, the time for last 10 power down and power on.

4.5 Recording the last 10 times for switch out and on by remote control, and also the time for switch out/on, power and etc.

4.6 Recording the total times for opening meter cover, the time for last 10 opening happened and finished.


5. Display

5.1 The following information would be displayed in meter:

5.2 The unit for power is kWh, and 8 digital display, including 2 decimals

5.3 LCD backlight wake up methods including switch wake up, infrared wake up(any infrared can work) and etc. In normal use, the life time for LCD won’t be less than 10 years

5.4 When power off, the backlight can be woke up by switch; If no operation after waking up, LCD would close automatically after a cycle; If operation exist, LCD would close automatically in 30 seconds after operation.

5.5 Indicator:

--Pulse Red, it is off in normal condition, and would be flash when measuring active power

--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.

6. Alarm

When the following faults or alarm appear, LCD would stop on the certain code and backlight keep on.

 

7. Freezing

Time Freezing: Freezing meter data according to the promissory time and interval; It can keep at least 12 times for each frozen fraction.

Instantaneous Freezing: Under improper condition, freezing current date time, all power and important measurement data; It keeps the data for last 3 times.

Appoint Freezing: In any case of older/new tariff, step tariff changeover and other situation which is necessary, the meter would freeze power and other important data on the changeover time, It keeps the data for last 2 times

Day Freezing: Store power on 0.00am for each day, total for 2 month

On Hour Freezing: Store active power for hour or half an hour, total for 96 data

8. Timing

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.

 

Safety precautions:
* 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.
* Never break the seals or open the front cover as this might influence the functionality of the meter.
* Do not through, drop, kick or other physical violence to the meter as there are high precision components inside that will break or make the meter measure inaccurate.
* Do not mount the meter in area's with harm gas, dust, mildew or insects or on unstable surfaces.
