Model
EM041DR
electricity meters
is a kind of three phase three 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
three 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.
