Abstract
DDS1550-LoRaWAN single phase Din rail LoRaWAN energy meter is an IOT energy measurement product with wireless communication. This product adopts the special large-scale integrated circuit, SOC high integration V9821S chip, enhanced 8052MCU core, integrated analog front end, RTC module. With a built-in LoRaWAN module, it can be connected to any standard LoraWAN gateway directly, you can easily build a wireless meter reading system.
LoRaWAN wireless technology relies on the advantages of easy deployment, low construction cost, and wide application environment. In addition, the LoRaWAN energy meter support bi-directional measurement, which makes it perfect for using with solar system.
The single-phase din rail LoRaWAN energy meter has active energy metering function, online display, intelligent anti-theft, remote centralized meter reading and etc. The measuring parameters include voltage (V), current (A), frequency (Hz), power (kW/kVAr/kVA), import / export / total energy (kWh/kVArh).

What is LoRa?
● LoRa stands for Long Range Radio. The wireless technology is mainly targeted for M2M and IoT networks, will enable public or multi-tenant networks to connect multiple applications running in the same network. LoRa technology will promote the developing of smart city with the help of LoRa sensors and automated products/applications.
● LoRa Alliance formed to standardize LPWAN (Low Power Wide Area Network) for M2M/IoT. The prospective members in this alliance are Actility, Cisco, Bouygues Telecom, Proximus, SingTel, Semtech, Swisscom, IBM, SingTel, KPN etc. The LoRa Alliance will drive global success of LoRa Protocol i.e. LORA WAN.
