Description
INTRODUCTION
The product 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 for smart buildings, factories, schools, hospital etc. However Built-in wireless Lora communication modem (more options as GPRS/3G/4G/NB-IoTÂ can collect the energy data from the meter and also transmit remotely directly to the server platform for energy data analysis.
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 also periodical freezing.
7. Event Record:
 Abnormal data: voltage, current, active power, demand, zeroing, trip, time calibration, programming, power loss, etc.
