1.Application

Model DEM311TH single phase electronic front board installed active energy meter is a kind of new style single phase two 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 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 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.

2. Functions and features

• Front board three fixed installation.
• Standard configuration 5+1 digits display (99999.1kWh) by step motor type impulse register. May selec 6+1 digits display(Product Configuration code is UC).
• Standard configuration one port of pulse output passive (polarity) May selec increase a distant port of pulse output passive(nonpolarity). And contact with all kind of AMR system convenientlyComplying with standard IEC 62053-31 and DIN 43864.
• Standard configuration only one LED instructions signal of energy impulse (red), may selec add instructions power supply state (green)and automatic detection the direction of the flow of load current and instructions by LED (when display yellow, that is meaning the direction of the flow of load current reverse). Please specified when ordering.
• 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.
• Direct connect operation, there are two types wiring you may select. Standard configuration type 1A wiring, may selec type  1B wiring (Product Configuration code is AH).
• Standard configuration extension terminals cover, in order to protect to use safety, may selec short terminals cover. (Product Configuration code is TG).
