Model
DEM021AB
Three Phase Three Wire
Electric Din-Rail Active Static Electric Energy Meter
is a kind of new style three phase three
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 three 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.
