3 Phase Din rail KWH meter

Kilowatt hour meter, Model GEM021DF three phase four wire electronic DIN rail active energy meter is a kind of new style three phase four 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 three phase active energy meter stipulated in international standard IEC 62053-21. It can accurately and directly measure 50Hz or 60Hz active energy consumption from three phase four wire AC electricity net. It can display total energy consumption by step and motor type impulse register. It has following features: Good reliability, small volume, light weight, specious nice appearance, convenient installation, etc. This meter has already got the patent certificate from Chinese national Intellectual Property Office at present. Patent certificate NO. ZL 2006 3 0107349.1, any other country patent certificate are in assessing.

Functions and features








35mm standard DIN rail installation, complying with standard DIN EN50022. Or front board setting (mounting holes center distance 63 mm), users can choose any one by themselves;
Ten pole width (Modulus 12.5mm), complying with standard JB/T7121-1993;
Standard configuration 6 digits display (999999kWh) by step and motor type impulse counter. May select 7 digits display by impulse counter (Product Configuration code is DJ);
There are a polarity port of pulse output passive closed and a no polarity port of pulse output passive distant, the output rate is 10 or 100 imp/KWh (can select). And contact with all kind of AMR system conveniently, complying with standard IEC 62053-31 and DIN 43864;
Five LED instructions respectively every power state and signal of closed power impulse and distant power impulse;
Automatic Detect the direction of the trend of load current. And instructions (signal of closed power impulse is green when working, that is meaning the load current reverse);
Single direction three components measure three phase four wire active power consumption. It is nothing with direction of the trend of load current. Complying with standard IEC 62053-21;
May select two components measure three phase three wire active energy (Product Configuration code is DE) or two phase three wire active energy (Product Configuration code is DD);
Standard configuration type S connection (Inlet from bottom, outlet from top) for direct connect to use, we can also choose another type of connection, and use 5+1 digits display by impulse counter, CT (Product Configuration code is CF) and PT & CT (Product Configuration code is BF) for operation;
Standard configuration extended terminals cover, may select short terminals cover, in order to protect to use electricity safely. (Product Configuration code is DI).
