Application

DTSF833/DSSF833 three-phase multi-rteelectric meter is a kind of three phase three tariffs (time-sharing billing)
active energy watt-hour 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, it is use for
setting indoor or out door meter box. 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,
light weight, specious nice appearance, convenient installation, etc.
