Model DEM021AB three phase three wire electronic DIN rail active energy meter is a kind of new style three 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 three phase three wire AC electricity net. This meter has seven digits LCD displays shows the active energy consumption. And there are far infrared and RS485 communication module in it. Contact with all kind of AMR system conveniently 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. ● Type S wiring (Inlet from bottom, outlet from top), use CT connect operation, may select set 27 ratio, after set the meter will direct reading when read, and haven’t multiplied by rate of CT. ● Seven digits display LCD, 5+2 digits display (99999.91 kWh, only ratio of CT when 5:5 A) or 7digits, it is choose by ratio of CT which is set. ● There are a polarity port of pulse output passive closed and a nonpolarity port of pulse output passive distant (the output rate is 10kWh/pulse). Complying with standard IEC 62053-31 and DIN 43864. ● Standard configuration there are a port of far infrared data communication and a port of RS485 data communication. Communication agreement complying with standard DL/T645-1997, can also choose without function of data communication. (Product Configuration code is NB). ● Five LED instructions respectively every power supply state (line voltage L12 & L32), signal of closed energy impulse and distant energy impulse and data communication state. ● Automatic detection the direction of the flow of load current. And Instructions on individual LCD ● Single direction two components measure three 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 short terminals cover, may select extension terminals cover, in order to protect to use safety. (Product Configuration code is AE). |
