Model DEM321MF three phase four wire electronic front board installed 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 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 batteries in it, use for showing blackout reading. It has following features: Good reliability, small volume, light weight, specious nice appearance, convenient installation, etc. |

| Front board three fixed installation, up and down mounting holes center distance is 198-212 mm, users can choose any one by themselves. Seven digits display LCD, standard configuration 6+1 digits display (999999.1kWh,). May select 5+2 digits display (Please specified when ordering). There is a maintenance-free lithium batteries in it, use for showing blackout reading. 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. Five LED instructions respectively power supply state and signal of closed energy impulse and distant energy impulse Automatic detection the direction of the flow of load current. And Instructions by individual LED. Single direction three components measure three phase four wire active energy consumption. It is nothing with direction of the flow of load current. Complying with standard IEC 62053-21. Standard configuration direct connect operation , type 16B wiring, we can also choose another type of wiring, and use CT (Product Configuration code is LF) and PT & CT (Product Configuration code is KF) for operation, it is type 5B wiring. Standard configuration extension terminals cover, in order to protect to use safety, may select short terminals cover. (Product Configuration code is MC).. |
