Model
DEM041BL three phase four wire electronic multi-rate DIN rail active
energy meter is a kind of three phase four wire two tariffs (tariff
conversion is controlled by timer outside or similar equipment)
active energy meter, 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 various consumption data and information.
And there are far infrared and RS485 communication module in it. It
is use for setting and reading the meter. 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.
