Description

The prouct is a din rail dc 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… Use 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.

Functions

  1. Multi-loop DC energy measuring with up to 6 loops.
  2. Each loop meter can measure the current combined energy, individually measure current, voltage, energy, power and electricity consumption of current month.
  3. Recording and alarming events like undervoltage, overvoltage, power failure , etc.
  4. Meter will automatically do the energy settlement on the auto meter reading day of each month. Data of last 24 months will be saved.
  5. Storing data of current, power, energy, time once every minute.
  6. Freezing data of current, power, energy, time once every hour.
  7. Storing monthly freezing energy of each month, the storage quantity is 24.
  8. Data inside the meter can be read through RS485 interface.
  9. Supporting broadcast time calibration. Remote time calibration can be realized through RS485 interface.
  10. Function of remote communication, telemetry, remote monitor, remote regulation.

Diagram

By wireless communication modem, modbus 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.
