Application                          MSM75SA

     The MSM75SA 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.  MSM75SA series energy meters technical performances completely conform to International Standards IEC 62053-21 for Class 1 single phase active energy meter.  MSM75SA 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.  MSM75SA series energy meters series have multiple types for option, to be suitable with the various market demands.  MSM75SA 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. ZL2012 3 0520871.8, any other country patent certificate are in assessing.

 

Functions and features

v MSM75SA series energy meters : Available as 35mm DIN standard rail mounted, conforming to Standards DIN EN 50022, as well as front PANEL mounted (the center distance between two mounting holes is 63mm or 67mm). Two mounted methods above are optional for user.

v MSM75SA series energy meters : 6 pole width (modulus 12.5mm), complying with Standards JB/T7121-1993.

v MSM75SA series energy meters :  6+1 digits (999999.1kWh) LCD display.

v MSM75SA series energy meters : Equipped with a polarity passive energy impulse output terminal, conforming to Standards IEC 62053-31 and DIN 43864.

v MSM75SA series energy meters : Two LEDs to indicate separately the power state (green) and the energy impulse signal (red).

v MSM75SA series energy meters :  Measure the active energy consumption in one direction on single phase two wire, which is not related with the load current flow direction at all, complying with Standards IEC 62053-21.

v MSM75SA series energy meters : Direct connection for use.

v MSM75SA series energy meters : The short terminal cover is made with the transparent PC, to reduce the installation space and is convenient for centralized installation.
