Long Life Front Active Single Phase Energy Meter DD862 for With Drum Wheel Register
Model YEM073QJ single phase electromechanical front board installed active energy meter is a kind of new style single phase two wire active energy meter, it is designed on the basis of original DD862 single phase electromechanical meter, and fully absorb new technologies about electromechanical meter from domestic and abroad. The meter completely accord with relevant technical requirements of class 2 single phase active energy meter stipulated in international standard IEC 62053-11. It can accurate and directly measure 50Hz or 60Hz active energy consumption from single phase AC electricity net, it is use for setting indoor or out door meter box. The meter has novel design, rational structure, and it can display total energy consumption by drum wheel mechanical register. It has following features: high overload, power loss, long-life, specious appearance, etc.
