Model
DEM481UC three phase four wire electronic multi-rate prepayment
front board installed active energy meter is a
kind of three phase
four wire active energy meter which purchase electricity by IC card,
electric energy measuring, load
control and using
electricity management. The meter completely accord with relevant
technical requirements of class 1
single 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, it is use for setting
indoor or out door
meter box. This meter has7 digits LCD monitors shows power. And there is
far infrared communication
module in it, can
read the meter and set the system parameters conveniently. It has
following features: Good reliability,
light weight,
specious nice appearance, convenient installation, etc.
