Single phase Din-rail Electronic Watt-hour Meter |
|
|
Type
DEM031 Single phase Din-rail Electronic Watt-hour Meter is a
kind of new style single phase electronic multi-rate watt-hour
meter, and energy data displaying adopts 7 digits wide temperature
type crystal display, with many functions of multi-rate (time-of
use) energy measurement, infrared carrier wave communication and
RS485 serial port communication reading meter, etc. The meter
completely accords with relevant technical requirements of class 1
and class 2 single phase energy meter stipulated in National
standard GB/T17215-2002 and international standard IEC61036. This Single
phase Din-rail Electronic Watt-hour Meter has following
features: Good reliability, small volume, light weight, specious
nice appearance, convenient installation, etc. |
