Functions and Features

1. The function of measuring forward active and reverse active electric energy, where the reverse electric energy is accumulated in the forward direction. It can measure, store and display the voltage, current, power, power factor, frequency and other operating parameters and status of the current electricity meter.
2. Remote blackout 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's load loop.
3. 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).
4. The communication protocol complies with DL/T645-2007 "Communication Protocol for Multifunctional Energy Meters".

And our lorawan electricity can widely used in such scenarios:
a.Residential quarters: smart meter reading, energy-saving management, and prevention of energy waste.
b.Commercial places: saving costs, improving energy efficiency, real-time monitoring.
c.Industrial enterprises: precise measurement, remote monitoring, energy saving and emission reduction.
d.Government agencies: Unify management, reduce operating costs, and improve energy management levels.
 

Display Description

 

After power on, the LCD screen will display fully for 3 seconds. Then display the current active electric energy and current active power. Alternate display.

Full display                                                                     Current active electric energy                              Current active power

 

Indicator display description

• Online: Constant light indicates that it has been connected to the           network. Off or flashing indicates no network access.
• Power off: the normally lit relay is disconnected. The extinction relay     is switched on.
• Pulse: flickers when measuring functional power. The power will be       off when there is no measurement.

 

RS485 Communication Interface

· The RS485 interface must be electrically isolated from the internal circuit of the energy meter and effectively protect the circuit.

· The RS485 interface should meet the electrical requirements of DL/T 645-2007. And can withstand an AC voltage of 380V for 2 minutes without damage.

· The communication rate of the RS485 interface can be set. The standard speeds are 1200bps, 2400bps, 4800bps, and 9600bps. The default value is 2400bps.

 

LoRaWAN Communication interface

· Interface communication rate is 9600bps, even parity check, 8-bit data bit

· Interface communication follows DL/T 645-2007 protocol and its filing documents

· After 10 seconds of powering on the electricity meter, communication can be carried out using the LoRaWAN interface.

· Active upload/bidirectional transparent transmission function: Actively upload data. The default interval for uploading data is 4 hours (the time can be set).

 

 

Wiring diagram

 

 

The main terminal wiring is shown in Figure 2. Among them, 1 is the phase line in, 2 is the phase line out, 3 is the zero line in, and 4 is the zero line out. There are 4 auxiliary terminals above the main terminals of the energy meter. Among them, 9 and 10 are metering pulse output, and 11 and 12 are 485 communication.

 

 

 

Note

INSTALLTION
Live installation of wiring is strictly prohibited!
The electricity meter shall be installed indoors as far as possible. Special instrument box protection shall be used for outdoor installation. The installation bottom plate shall be fixed on the wall with strong fire resistance and not easy to vibration. There must be no corrosive gases in the surrounding air where the meter is installed. Avoid dust, salt spray, etc.
When using the electricity meter, the wiring must be conducted strictly according to the wiring diagram in the tail cover of the meter. It is recommended to use copper wire for the lead connected to the terminal seat. The screws of the fixed lead in the terminal seat should be tightened to avoid burning the electricity meter due to bad contact and heating.
