Product Description：
Traditional single-phase electricity meters suffer from limited accuracy, restricted communication options, and a lack of real-time data, often leading to billing disputes and high O&M costs while making it difficult for users to effectively monitor and conserve electricity.
The Hexcell DDS1088/DDSY1088 utilizes advanced SMT technology and supports RS485, IEC62056-21 optical ports, and LoRa connectivity. It enables remote data transmission and real-time electricity usage monitoring, helping users manage consumption, reduce costs, and support energy conservation and emission reduction.
It features Class 1 active and Class 2 reactive energy accuracy, a wide voltage and current operating range, and IP51/IP54 protection. It holds comprehensive certifications (IEC, ISO9001, STS, KEMA, DLMS), offers a service life exceeding 10 years, and supports optional 12-month data storage and multi-tariff capabilities. Its performance has been proven in residential, commercial, and photovoltaic applications.
