LCD Display Digital Energy Meter Three Phase 3P3W / 3P4W For Voltage
Introduction:
DTS150 series FBR(LoRaWAN) three phase four wire electric energy meter adopts advanced SMT production design and manufacture. Besides measure active energy, it also has function for online power display, smart anti-tamper, overload control, remote meter reading and etc.
It sends data to corresponding gateway through LoRaWAN wireless network. It has advantages in high accuracy, low power consumption, and good stability that can be widely used for the single phase alternating current in city, rural areas or factory enterprises, etc.

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.
(2) Total active energy
When a circle appears at the top right of the display, it indicates that the value is the total active energy.
The figure shows that the current total active energy is 2.25kWh.
(3) The electricity of phase A, B, C.
When a circle appears at the upper left of the display, it indicates that the value is electricity of phase A.
The figure shows that the current electricity of phase A is 2.25kWh.
The figure shows that the current electricity of phase B is 2.25kWh.
The figure shows that the current electricity of phase C is 2.25kWh.
(4) The meter number
The figure shows that the current meter number is 1234.
(5) The indicator description 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 LoRaWan communication module is connecting to the network, and the indicator is always on when the connection is completed.
Data: When the LoRaWan communication module receives and sends data, the indicator light will flashes.
Appearance:
QR code: Including product model, product communication address, product specifications (voltage, current), communication protocol.
