Application                   MSM18SA
     MSM18SA is DIN rail single phase two wire active electronic energy meter. It adopts 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. The technical performances completely conform to International Standards IEC 62053-21 for Class 1 single phase active energy meter. It can directly and accurately measure the load active energy consumption in the single phase AC networks of rated frequency 50Hz or 60Hz. MSM18SA  has features with excellent long-term reliability, small volume, light weight, perfect appearance, easy installation, etc.This meter has already got the patent certificate from China State Intellectual Property Office at present. Patent certificate NO.ZL  2012 3 0473770.X, any other country patent certificate are in assessing.
