| Application |
|
Model DEM041AR three phase four wire electronic multi-rate DIN rail active energy meter is a kind of three phase four wire three tariffs (time-sharing billing) active energy meter, 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 four wire AC electricity net. This meter has seven digits LCD displays shows various consumption data and information. And there are far infrared and RS485 communication module in it. It is use for setting and reading the meter. 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.

| Functions and features |
● 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 27 CT ratio, the meter will read directly after set, and needn’t multiplied by CT rate.
● Have three tariffs, may select 12 daily period of times. You can set the date arbitrary which can automatic read the meter every month. May select single tariff function in weekend. (Please specified when ordering)
● There are a clock and Maintenance-free backup lithium batteries in it. Battery capacity detection and display all the time. It can keep the electricity data for 12 months. The data can be kept forever after blackout.
● May select cycle display (default) or push the button itemized display, we can set the cycle display, it can display 14 data at most. Can select the data which displayed. Data 5+2 digits(99999.91kWh, Only when CT ratio 5:5A) or 7 digits display. It is choose by the CT ratio 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 10 kWh/ Pulse), Complying with standard IEC 62053-31 and DIN 43864.
● There are far infrared and a port of RS485 communication data. It is use for setting and reading the meter. Set and operation have password protection, communication agreement complying with standard DL/T645-1997.
● Ten LED instructions respectively power supply state, signal of energy impulse, the direction of the flow of load current, the tariff state just now and the data communications state.
● 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 short terminals cover, may select extension terminals cover, in order to protect to use safety. (Product Configuration code is AS). |
