Application |
Model
DEM021JA two phase three wire electronic DIN
rail active energy meter is a kind of new
style two 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 accurate and directly
measure 50Hz or 60Hz active energy
consumption from two phase three wire AC
electricity net. This meter has seven digits
LCD displays shows the active energy
consumption. 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 China State
Intellectual Property Office at present.
Patent certificate NO. ZL 2006 3 0107349.1,
any other country patent certificate are in
assessing..
