Model
DEM041AR three phase four wire electronic multi-rate DIN rail active
energy meter is a kind of three phase four wire
three tariffs (time-sharing billing) 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 accurately
and directly measure 50Hz or 60Hz active energy consumption from
three phase four wire 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 0107349.1, any other country patent
certificate are in assessing.
