Hop super hot sale single phase tariff control Lora laser energy meter in new electricity
Please feel free to contact us if you are interested in our laser energy meter
DDZY1737 is a wall mounted single-phase tariff control smart energy meter with backlight LCD display. It is a smart energy manage meter with software platform for a total solution in smart buildings, factories, schools, hospital 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.
Hop smart energy meter is adaptable for time difference in different countries, even keeping 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.

System Diagram

With built-in wireless communication modem, 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.
Features & Advantages

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 at least 2 months to avoid data loss in case of network gone.
4. Remotely upgradable:
The internal program of 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.
