Model
DEM021AC
Three Phase Four Wire
Electric Din-Rail Mounted Active Energy Meter
is a kind of new style three phase four
wire active energy
meter, it adopt micro-electronics technique, and imported large scale
integrate circuit, use advanced
technique of
digital and SMT techniques, etc. 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 the active energy power consumption. And there are far infrared
and RS485 communication
module in it.
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.
