APPLICATION

EM314TL SINGLE PHASE THREE WIRE ELECTRONIC FRONT BOARD INSTALLED ACTIVE ENERGY METER

Application
Model EM314TL single phase three wire electronic front board installed active energy meter is a kind of new style single phase three wire active energy meter, it 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 National standard IEC 62053-21. It can accurately and directly measure 50Hz or 60Hz active energy consumption from single phase three wire AC electricity net, it is use for setting indoor or out door, and it can display total energy consumption by step motor type impulse register. 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.
● 5+1 digits display (99999.1kWh) by step motor type impulse register.
● 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 measure single phase three wire active energy consumption. It is nothing with direction of the flow of load current. Complying with standard IEC 62053-21.
● Direct connect operation, type 2A wiring.
● Standard configuration extension terminals cover, in order to protect to use safety, may select short terminals cover. (Product Configuration code is TK).
