Application                   MSM75S-U

 Model MSM75S-U single phase electronic DIN rail active energy meter is a kind of new style single phase two wire active energy meter, it adopt micro-electronics technique, and imported large scale integrate circuit, use advanced technique of digital and SMT techniques, etc. The meter completely accord with relevant technical requirements of class 1 single phase active energy meter stipulated in international standard IEC 62053-21. It can accurate and directly measure 50Hz or 60Hz active energy consumption from single phase AC electricity net, it can display total energy consumption by step motor type impulse register. It has following features: good reliability, small volume, light weight, specious nice appearance, convenient 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.

Functions and features
 v MSM75S-U series energy meters; 35mm standard DIN rail installation, complying with standard DIN EN50022. 
 v MSM75S-U series energy meters;  Six pole width (Modulus 12.5mm), complying with standard GB/T7121-1993.
 v MSM75S-U series energy meters;  Standard configuration 5+1 digits display (99999.1kWh) by step motor type impulse register.
 v MSM75S-U series energy meters;  Standard configuration one port ,complying with standard IEC 62053-31 and DIN 43864.
 v MSM75S-U series energy meters;  Two LED instructions power supply state (green) and signal of energy impulse (red).
 v MSM75S-U series energy meters;  Standard configuration don抰 detection direction of the flow of load current. May select automatic detection the direction of the flow of load current. And instructions (Only red energy impulse signal when working, that is meaning the direction of the flow of load current reverse).
 v MSM75S-U series energy meters;  Single direction measure single phase two wire active energy consumption. It is nothing with direction of the flow of load current. Complying with standard IEC 62053-21.
 v MSM75S-U series energy meters; Standard configuration short terminals cover, may select extension terminals cover, in order to protect to use safety.
