DEM471UA Single phase Active Energy Meter (China)

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.

--Payment by money, standard configuration with one meter one card, can repeat input

money from PC machine which with IC programmer.

--Have three tariffs, may select 4 time area, every time area can set 12 daily period, every

time area has one rate, every rate can set three unit price.
