The DDS-1 series are socket mounted single phase electronic active energy meters. They adopt many advanced technologies of research and development, like microelectronic-techniques, specialized large-scale IC (integrated circuit), digital sampling and processing technology, SMT technique, and so on. Their technical performances completely conform to International Standards IEC 62053-21 for Class 1 single phase active energy meter and Standards ANSI C12.1, C12.10, C12.20. They can directly and accurately measure the load active energy consumption in the single phase two wire & three wire AC networks of rated frequency 50Hz or 60Hz and used indoors or outdoors. They have features with excellent long-term reliability, small volume, light weight, perfect appearance, easy installation, etc.
