Hop Manufacturer Single Phase Power Current Measuring RS485 Port Smart Energy Meter with Lora Communication

DDZY1737 is a wall-mounted single-phase tariff control smart energy meter with a backlight LCD display. It is a smart energy management meter with a software platform for a total solution in smart buildings, factories, schools, hospitals, etc... Built-in wireless Lora communication modem (more options as GPRS/3G/4G/NB-IoT) can collect the energy data from the meter and transmit remotely directly to the server platform for energy data analysis. 

#Parameters#

Hop smart energy meter is adaptable for the time difference in different countries, even keeping the same time zone with the software platform.

In the case of no network, the data can be stored in our meter max.  one year (depends on how much data) until the network communication recovers.

With a built-in wireless communication modem, the Lora modem, the meter can transmit the energy data directly to the server platform. The communication modem is flexible and changeable according to the local network situation. Metering and transmission two-in-one design is an excellent combination with advantages of cost-saving, simple construction, quick deployment.

#Functions#

1. Metering & Measurement:

    Current, voltage, power factor, active power, daily energy, energy consumption

2. Communications:

    Built-in Lora modem with plug-and-play design.

    More options: GPRS/3/4G, NB-IoT, etc.

    Transmitting data directly to the server platform.

3. Remote Power on/off Switch Control:

    Relay built-in answers the Switch on/off command from the server platform to remotely control the power on/off.

4. Data Storage:

    Energy data stored in the modem traceable and retrievable in case of GPRS or other network disruption.

    Storage up to one year to avoid data loss.

5. Display:

    Backlight LCD display screen with various status indicators.

6. Energy Freezing:

    Time freezing, instantaneous freezing, daily freezing, contract freezing, and periodical freezing.

7. Event Record:

    Abnormal data: voltage, current, active power, demand, zeroing, trip, time calibration, programming, power loss, etc.

 

1. Simple Construction:

    Robust design with communication modem built in the meter.

2. Save cost:

    Electricity meter + gateway two-in-one, no need external DTU device, no need RS485  wiring, saving equipment, materials and labor costs.

3. Data Storage Retrievable:

    With great capacity, the GPRS modem can store energy data for at least 2 months to avoid data loss in case of network gone.

4. Remotely upgradable:

    The internal program of the communication modem can be remotely upgraded, which is convenient for aftersales system maintenance.

5.  Automatic reading without manual:

     Remote reading of meter data through communication modem to reduce on-site labor costs.

6. Flexible Communication Selection:

    The communication module can be selected according to the local network mode, for example, GPRS, 3G, 4G, and NB-IoT can be selected to achieve a matching network connection.

7. Two payment solutions available:

    Pre-payment and post-payment.

#FAQ#

Q: Do you have an APP for the energy meter?

A: Since different areas' clients have different using habits, so APP is always customized for clients according to the developing instructions clients give.

Q: Can the smart energy meter support wireless communication?

A: Yes, our wall-mounted energy meter is with built-in communication modem; and din rail energy meter needs to be connected to an external data collector/DTU with a communication modem.

Q: Can you put our logo on the smart energy meter, DTU and software?

A: Yes, we can put your logo on the meter, data collector(concentrator) and system software.

Q: Can I confirm whether the communication is successful through the indicator light on the meter?

A: Yes. From the two status indicators of the meter, you can identify the communication status of the meter network;  When the green light flashes, the communication module works normally.

Q: If the load of 100A needs to be switched off, can you achieve it with your electricity meter?

A: 100A load can be pulled, but the circuit breaker (outer pull) needs to be configured, and the 60A meter can be pulled by the internal relay breaker.
