Model DEM021DD two phase three wire electronic DIN rail active energy meter is a kind of new style two 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 three phase active energy meter stipulated in international standard IEC 62053-21. It can accurate and directly measure 50Hz or 60Hz active energy consumption from two phase three wire AC electricity net. It can display total energy consumption by step motor 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 China State Intellectual Property Office at present. Patent certificate NO. ZL 2006 3 0107349.1, any other country patent certificate are in assessing. |

| ● 35mm standard DIN rail installation, complying with standard DIN EN50022. Or front board installed (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 motor impulse register. May select 7 digits display by impulse register (Product Configuration code is BJ). ● There are a polarity port of pulse output passive closed and a nonpolarity 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. ● Four LED instructions respectively power supply state (phase voltage L1 & L3) and signal of closed energy impulse and distant energy impulse. ● Automatic detection the direction of the flow of load current. And instructions (signal of closed energy impulse is green when working, that is meaning the direction of the flow of load current reverse). ● Single direction two components measure two phase three wire active energy consumption. It is nothing with direction of the flow of load current. Complying with standard IEC 62053-21. ● Standard configuration type S wiring (Inlet from bottom, outlet from top) for direct connect operation, we can also choose another type of wiring, and use 5+1 digits display by impulse register, CT (Product Configuration code is CD) and PT & CT (Product Configuration code is BD) for operation. ● Standard configuration short terminals cover, may select extension terminals cover, in order to protect to use safety. (Product Configuration code is DG). |
