Two Phase Three Wire
Electric Din-Rail Active Watthour Power 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 internationall standard IEC 62053-21.
It can accurately and directly
measure 50Hz or
60Hz active energy consumption from two phase three wire AC electricity
net. This meter has seven
digits LCD monitors
shows the active energy power 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
Chinese national Intellectual Property Office at present. Patent
certificate NO. ZL 2006 3 0107349.1,
any other country
patent certificate are in assessing.
