Display description:

After power supply, the LCD is fully displayed for 5 seconds, then the LCD will show the total power

and shunt power, then it will show the meter number. Each item is continuously displayed for 5

seconds. If there is a phase loss, the LCD will appear a corresponding indication.

(1) Fully Display

The figure shows that the current electricity of phase B is 2.25kWh.

NB-IoT Wireless Remote Three Phase Prepaid Meter 5

 

The figure shows that the current electricity of phase C is 2.25kWh.

(4) The meter number

NB-IoT Wireless Remote Three Phase Prepaid Meter 6

 

The figure shows that the current meter number is 1234.

(5) The indicator description

NB-IoT Wireless Remote Three Phase Prepaid Meter 7

Pulse: The indicator flashes when the user is using power.

A.B.C: Indicates whether the phase A.B.C is out of power. For example, when phase A has no

voltage, the phase A indicator will light to remind the user.

Off: The indicator will light up when the internal relay is disconnected.

Online: The indicator flashes when the NB-IoT communication module is connecting to the

network, and the indicator is always on when the connection is completed.

 

NB-IoT Communication Interface:

Using NB-IoT communication for meter reading and parameter setting. When meter reading. It is also possible to design a software and hardware system that fully complies with the protocol requirements for meter reading and parameter setting according to the power industry standard DL/T 645-2007 (supporting part of the communication protocol).

In-built NB-IoT communication module support upload data actively, and start/stop active uploading through communication setting.

 

Carriage and storage:

Our products should be packaged well when being transported. And the products should not be shaken or hit when being transported and unpacked. The carriage and storage should correspond with GB/T15464-1995 "General packing technical conditions of instruments and meters" Inventory and storage should be put on the bracket under the original package, and the stacked height can’t exceed 5 layers. The storage place will be clean and the environment temperature will not more than from -40℃ to +70℃, relative humidity not more than 95% and without corrosive gas and mildew in the air.

 

Dimension(218mm×145mm×72mm):

(1) The electric meter should be installed indoors and installed on the wall or in the meter box. The

electric meter should be basically vertical when installing.

(2) The voltage to be connected should meet the rated operating voltage, and the current should

not exceed the maximum rated current.

(3) In the case of power failure, the wiring should be strictly as shown in the wiring diagram.

(4) The electric meter is fixed on the meter box with three screws.
