DDS155 LoRaWAN Smart Meter , 2P DIN Rail Single Phase Elecrtric Meter
Description:
DDS155G2R-LoRaWAN single phase DIN electric meter is an all-digital electricity metering and monitoring IoT product developed by our company. It adopts SOC high integration V9821S chip, with active energy metering function, online display, intelligent anti-theft, remote centralized meter reading and other functions. Data is transmitted to the corresponding gateway through the LoRaWAN wireless ad hoc network. It adopts 2P DIN Rail type meter case design, which has the advantages of small size, high precision, low power consumption, good stability and convenient installation. It can be widely used in city, country or any enterprise.
G2R: 2P DIN Rail single phase electric meter, LoRaWAN, External antenna
