APPLICATION

EM314DS SINGLE PHASE ELECTRONIC FRONT BOARD INSTALLED ACTIVE ENERGY METER

Application
Model EM314DS single phase electronic front board installed active energy meter is adopt micro-electronics technique, and imported large scale integrate circuit, use advanced technique of digital and SMT techniques, etc. 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 accurate and directly measure 50Hz or 60Hz active energy consumption from single phase AC electricity net, it is use for setting indoor or out door, and this meter has seven digits LCD displays shows the active energy consumption. And there is a maintenance-free lithium battery in it, use for displaying power cut reading. It has following features: good reliability, small volume, light weight, specious nice appearance, convenient installation, etc.

Functions and features
● Front board three fixed installation, up and down mounting holes center distance is 126-141 mm, users can choose any one by themselves.
● Seven digits display LCD, standard configuration 6+1 digits display (999999.1kWh). May select 5+2 digits display (Please specified when ordering).
● There is a maintenance-free lithium battery in it, use for displaying power cut reading.
● Standard configuration one port of pulse output passive (polarity), May select increase a distant port of pulse output passive (nonpolarity). And contact with all kind of AMR system conveniently, Complying with standard IEC 62053-31 and DIN 43864.
● Two LED instructions signal of energy impulse (red) and direction of the flow of load current (yellow).
● Automatic detection the direction of the flow of load current. And when only yellow LED display, that is meaning the direction of the flow of load current reverse.
● Single direction single component measurement single phase two wire active energy consumption. It is nothing with direction of the flow of load current. Complying with standard IEC 62053-21.
● Direct connect operation, there are two types wiring you may select. Standard configuration type 1A wiring, may select type 1B wiring (Product Configuration code is MF).
● Standard configuration extension terminals cover, in order to protect to use safety, may select short terminals cover. (Product Configuration code is DR).
