DEM421GC Electricity Meter
Three phase Four wire electronic Din-Rail Active and Integration Electricity Meter |
|
|
Electricity Meter Application |
|
Model
DEM421GC three phase four wire electronic DIN rail active and
reactive integration Electricity Meter is a kind of new
style three phase
four wire active and reactive integration Electricity 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
Electricity Meter stipulated in international
standard IEC
62053-21 and class 2 three phase reactive Electricity Meter stipulated in
international standard IEC 62053-23.
It can accurately
and directly measure 50Hz or 60Hz active energy consumption from three
phase four wire AC
electricity net, it
can display total energy consumption by step type impulse register. This
meter has seven digits LCD
monitors shows
active power. 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.
