WiFi Single Phase Smart Electric Energy Meter with Prepaid Remote Control and Electricity on-off Control, Time-Based Billing

WiFi Single Phase Smart Electric Energy Meter with Prepaid Remote Control and Electricity on-off Control, Time-Based Billing

The intelligent electricity meter has the functions of electric energy measurement, power parameter measurement, time-sharing measurement, real-time freezing, on-off control, WiFi communication etc. It has the advantages of long communication distance, large capacity, fast and convenient installation, and long service life.

Our Advantages

1.Measure Forward and Reverse Active Energy: Electrical energy should be accumulated and stored separately for electric energy and total electrical energy at each time period such as tips, peaks, flats, and valleys. And it can also store and display the power of the previous 12 months.

2.It can measure,store and display the voltage, current, power, power factor, frequency and other operating parameters and status of the current electricity meter. And it has overload protection function.

3.There are two sets of rates (sharp, peak, flat, valley) and periods that can be programmed arbitrarily, and another set of rates and periods can be start to used at the set time point. Each set of rate time periods can be set with at least 2 time zones for a year. At least 14 time periods can be set within 24 hours. The minimum time period interval is 15 minutes. The time period can be set across zero points.

4.It has freezing functions such as instantaneous freezing, regular freezing, daily freezing, agreed freezing and hour freezing.

5.It has the function of event recording such as zero clearing, programming, proofread, power down, pulling and closing the brake, etc.

6.Remote disconnection and power transmission function. Power off command is issued through communication interface such as RS485 to cut off the user's load loop; Or issue a power transmission instruction to turn on the user load loop.

7.Active upload / bidirectional transparent transmission function. Actively upload the data to the corresponding platform through the LoRaWAN wireless network, with a default interval of 4 hours (settable).

8.After the meter is powered on and the LoRaWAN module is connected to the network, the meter is automatically calibrated.
