DEM051AO

SINGLE PHASE ELECTRONIC FRONT BOARD INSTALLED MULTIFUNCTIONAL ENERGY METER
 
 
Application

Model DEM051AO single phase four wire electronic multifunctional front board installed energy meter is a kind of new style single phase multifunctional energy meter. The meter completely accord with relevant technical requirements of class 1 single phase active energy meter stipulated in international standard IEC 62053-21 and class 2 single phase reactive energy meter in international standard IEC 62053-23. It can accurately and directly measure 50Hz or 60Hz active energy consumption from single phase AC electricity net, This meter has LCD monitors shows the active energy power consumption, and there are far infrared and RS485 communication module in it, contact with all kind of AMR system conveniently. It has following features: Good reliability, small volume, light weight, specious nice appearance, convenient installation, etc.

 
 
Functions and features
Front board three fixed holes installation, the cover is made of PC material which is transparent and anti-UV molded overall, the base of the meter and the terminal block is made of quality bakelite material which is moisture-resistant, fire-retardant, high temperature molded overall. It has following features: good weather ability, high rigid, good insulation performance, etc.
