Wall Mounted Single Phase Energy Meter

INTRODUCTION

The DDZY737 single phase electricity meter 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.

FUNCTIONS

1. Metering & Measurement:

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

2. Communications:

Built in communication module with plug-and-play design.

Supported communication mothod: GPRS, 2/3/4G, NB-IoT, Wi-Fi, Lora, 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 meter traceable and retrievable in case of 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.
