Application                         MSM75SD-U

     The MSM75SD-U series energy meters are DIN rail single phase two wire active electronic energy meters. The energy meters 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.  MSM75SD-U series energy meters technical performances completely conform to International Standards IEC 62053-21 for Class 1 single phase active energy meter.  MSM75SD-U series energy meters can directly and accurately measure the load active energy consumption in the single phase AC networks of rated frequency 50Hz or 60Hz. And there are far infrared and RS485 communication module in it. MSM75SD-U series energy meters series have multiple types for option, to be suitable with the various market demands.  MSM75SD-U series energy meters have 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 2013 3 0556103.2, , any other country patent certificate are in assessing.
