Application |
|
Model
DEM471UA single phase electronic multi-rate prepayment front board
installed active energy meter is a kind of
single phase two
wire active energy meter which purchase electricity by IC card, electric
energy measuring, three tariffs
(time-sharing
billing), ladder rate, 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 single phase AC
electricity net, it
is use install in meter box indoor or out door. This meter has 7 digits
LCD monitors shows various
consumption data
and information. 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.
