Application                       MSM1250S                                                              

The MSM1250S series power meters are DIN rail three phase active electronic energy meters. They adopt many advanced technologies of research and development for the power meters, like microelectronic-techniques, specialized large-scale IC (integrated circuit), digital sampling and processing technology, SMT technique, and so on. Their technical performances of power meters completely conform to International Standards IEC 62053-21 for Class 1 three phase active energy meter. MSM1250S series power meters can directly and accurately measure the load active energy consumption in the three phase AC networks of rated frequency 50Hz or 60Hz. The MSM1250S series power meters have multiple types for option, to be suitable with the various market demands. MSM1250S series power meters have features with excellent long-term reliability, small volume, light weight, perfect appearance, easy installation, etc.
