AMR System Single Phase Energy Meter, 1 Phase Electronic Meter with Li Battery
Model YEM311MF 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 cup reading. It has following features: good reliability, small volume, light weight, specious nice appearance, convenient installation, etc.

1. Front board three fixed installation.
2. Seven digits display LCD, standard configuration 6+1 digits display (999999.1kWh). May select 5+2 digits display (Please specified when ordering).
3. There is a maintenance-free lithium battery in it, use for showing blackout reading.
4. 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.
5. Two LED instructions power supply state (green) and signal of energy impulse (red).
6. Automatic detection the direction of the flow of load current. And instructions by individual LED. (Only yellow energy pulse signal when working, that is meaning the direction of the flow of load current reverse).
7. Single direction single component measure single phase two wire active energy consumption. It is nothing with direction of the flow of load current. Complying with standard IEC 62053-21
8. Direct connect operation, there are two types wiring you may select. Standard configuration type 1B wiring, may select type 1A wiring (Product Configuration code is DS).
9. Standard configuration extension terminals cover, in order to protect to use safety, may select short terminals cover. (Product Configuration code is MC).
