Application

Model DEM041DR three phase three wireelectronic multi-rate DIN rail active energy meter is a kind ofthree phase three wire three tariffs (time-sharing billing)activeenergy meter, the meter completely accord with relevant technicalrequirements of class 1 three phase active energy meter stipulatedin international standard IEC 62053-21. It can accurate anddirectly measure 50Hz or 60Hz active energy consumption from threephase three wire AC electricity net. This meter has seven digitsLCD displays shows various consumption data and information. Andthere are far infrared and RS485 communication module in it. It isuse for setting and reading the meter. Contact with all kind of AMR systemconveniently. It hasfollowing features: good reliability, small volume, light weight,specious nice appearance, convenient installation, etc. This meterhas already got the patent certificate from China State Intellectual Property Office atpresent. Patentcertificate NO. ZL 20063 0107349.1, any othercountry patent certificate are in assessing.

 Functions andfeatures

- 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 bythemselves.

- Ten pole width (Modulus 12.5mm), complying with standardJB/T7121-1993.

- Type S wiring (Inlet from bottom, outlet fromtop),use CT connectoperation, may select 27CT ratio, the meter will read directly after set, and needn’tmultiplied by CT rate.

- Havethree tariffs, may select 12 daily period of times. You can set thedate arbitrary which can automatic read the meter every month. Mayselect single tariff function in weekend. (Please specified whenordering)

- There are a clock and Maintenance-free backuplithium batteries in it. Battery capacity detection and display allthe time. It can keep the electricity data for 12 months. The datacan be kept forever after blackout.

- May select cycle display (default) orpush the button itemized display, we can set the cycle display, itcan display 15 data at most. Can select the data which displayed.Data 5 2 digits(99999.91kWh,only when CT ratio 5:5A) or 7 digitsdisplay. It is choose by the CT ratio which isset.

- There are a polarity port of pulse output passiveclosed and a no polarity port of pulse output passive distant, theoutput rate is 10kWh / Pulse). Complying with standard IEC 62053-31and DIN 43864.

- There are far infrared and a port of RS485communication data. It is use for setting and reading the meter.Set and operation have password protection, communication agreementcomplying with standard DL/T645-1997.

- Nine LED instructions respectively powersupply state, signalof energyimpulse, thedirection ofthe flow of load current,the tariffstate justnowand thedatacommunications state.

- Single direction two components measurethree phase three wire active energy consumption. It is nothing withdirection of the flow of load current. Complying with standard IEC62053-21.

- Standard configuration short terminals cover,may select extension terminals cover, in order to protect to usesafety. (Product Configuration code is DS).
