Meba electromechanical socket power meter MB351PB  is a kind of new style single phase three 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 and standard ANSI C12.10-1997. It can accurate and directly measure 50Hz or 60Hz active energy consumption from three phase AC electricity net, it is use for setting indoor or outdoor meter box. This meter has 7 digits LCD displays shows power. And there is far infrared communication module in it, can read the meter and set the system parameters conveniently, it has following features: good reliability, light weight, specious nice appearance, convenient installation, etc.
