New-Style Single Phase LoRaWAN Electric Meter with LCD Display
Single phase electronic meter is a full digital intelligent
metering with special clip which function for e-management and also
can prevent from electricity stolen. It can widely used in city,
country or school and any enterprise.
DDS155 series BR (LoRaWAN) single phase electric meter is a kind of
fully digitized energy meter which adopts the SOC high-density
V9821S chip.
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.
Features:
1. Product's Type: Register (5+1), LCD (5+1 or 6+2), LED(5+1).
2. Electric Power Measurement: Positive active power, reverse
active power and power in A, B, C phase which can be measured.
3. Intelligent Design: Imported single-chip which controlled by
microcomputer, full digital metering, with advantages of high
accuracy, good linearity, wide range, low consumption and prevent
from electricity stolen.
4. Reliable Design: Perfect power source and electromagnetism
compatible design, which are suitable to the strong
electromagnetism disturbance and big occasion of power source
fluctuation.
5. Cover for Meter: Fully sealed dustproof and waterproof design,
material of cover has excellent flame retardant and anti-corrosion,
anti-aging properties.
6. On-Off Manner: Build in or external switch can be optional.
7. Communication Mode: Infrared, RS485 interface or carrier
communication module (Optional).

LoRaWAN communication interface:
Using LoRaWAN communication for meter reading and parameter
setting. When meter reading, remote meter data transmission
software provided by our company can be used for meter reading and
parameter setting. 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).
Please take attention to the following points when handle meter
reading and parameter setting:
a. Parameter setting, please just setting items which refers to the
certain meter.
b. LoRaWAN active upload data format:
