Function Description
Electricity Metering
Active and reactive electric energy.
2 Live Measurement
It measures real-time voltage, current, active power, power factor, and more. Measurement error (reference error) does not exceed ±1%.
Remote on/off circuit breaker
Built-in load switch; the electricity meter can output signals to control the load switch, paired with 4G/485 communication, enabling remote manual opening and closing of the circuit breaker.
4 LED Indication, Pulse Signal Output
The electrical panel is equipped with LED indicator lights: circuit breaker, pulse, and network indicators.
5. Power Pulse
Indicate pulse output, power pulse constant of 6400 imp/kWh (external) or 400 imp/kWh (direct).
6. 4G signal light
Indicate whether the electrical energy meter is connected to the network, as follows:
The indicator blinks, indicating entry into the smart networking mode; the indicator stays solid without blinking, meaning the electricity meter is online, paired, and ready for remote management upon confirmation of a stable internet connection.
7. Alarm Indicator
a) Constant illumination, indicating that the power meter has been disconnected.
8. 4G Communication (Optional)
The built-in 4G communication module ensures that the communication function will not affect the performance, operating parameters, or normal measurement of the electricity meter.
Upon powering on, the electricity meter's 4G module automatically searches for and connects to the nearest base station to access the 4G network. If the signal inside the building is weak, an external antenna can be connected to extend to an open area with good signal reception, facilitating the electricity meter's network connection.
9. 485 Communication
The electric energy meter features a 485 communication interface, which allows for independent communication with the meter via the 485 terminal, or connection to a collector through the same terminal. Damage to the interface does not affect the operation of other interfaces. The communication interface and the internal circuit of the meter are optically isolated, with a failure protection circuit in place.
10. Remote Functionality
Once successfully connected to the internet, the electricity meter is connected to our company's server, working in conjunction with our backend system to enable multiple remote functions, including:
a) Admin PC, wireless remote meter reading, switch on/off, remote management
b) Users can remotely recharge via the WeChat Mini Program and receive push notifications through the official account.
Dimensions and wiring diagram
Dimensions Drawing
Wiring diagram
This series of multifunctional smart electricity meters supports two wiring methods: direct connection and connection via a current transformer (CT).
Note: Please refer to the product manual's wiring diagram for actual wiring.
Installation Precautions and Methods
The instrument should be installed using the 35mm standard track method in a well-ventilated and dry indoor location.
2. When installing wiring, follow the wiring diagram on the physical side of the instrument. It's best to have copper wire terminals connected. For direct wiring instruments, pay attention to the incoming and outgoing line directions and tighten the screws to prevent abnormal operation of the instrument due to poor contact; when wiring instruments connected through current transformers, note the polarity of the transformer's secondary.
