DEM031AL

Model DEM031AL single phase electronic multi-rate DIN rail active energy meter is a kind of single phase two wire three tariffs (time-sharing billing)active energy meter, 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 accurately and directly measure 50Hz or 60Hz active energy consumption from single phase AC electricity net. This meter has seven digits LCD monitors shows various consumption data and information. And there are far infrared and RS485 communication module in it. It is use for setting and reading the meter. Contact with all kind of AMR system conveniently. 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 Chinese national Intellectual Property Office at present. Patent certificate NO. ZL 2006 3 0106828.1, any other country patent certificate are in assessing.
