Meba power meterings MB024SC is a kind of new style three phase four wire electronic active energy meter, it adopt micro-electronics technique, and imported large scale integrate circuit, use advanced technique of digital and SMT techniques, etc. It has its completely independent intellectual property rights and minimum size, and also a new three phase four wire active energy meter. The meter completely accord with relevant technical requirements of class 1 three phase active energy meter stipulated in international standard IEC 62053-21. It can accurate and directly measure 50Hz or 60Hz active energy consumption from three phase four wire 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. The patent certificate of this meter is in assessing in the China State Intellectual Property Office at present.
