|
| Application Type DEM031 single phase DIN rail watt-hour meter is a kind of new style single phase electronic multi-rate watt-hour meter, energy data display adopt 7 digits wide temperature type crystal display, with many functions of multi-rate (time-of use) energy measurement, infrared carrier wave communication and RS485 serial port communication reading meter, etc. The meter completely accord with relevant technical requirements of class 1 and class 2 single phase energy meter stipulated in National standard GB/T17215-2002 and international standard IEC61036. it has following features: Good reliability, small volume, light weight, specious nice appearance, convenient installation, etc.1. May select 35mm DIN rail installation or installation on the board. 2. Have 3 tariffs, 12 daily period of times, may select single tariff function in weekend. 3. Inner emplaced clock, after power cut down, the message is preserved forever, inner emplaced spare batteries and free of maintenance. 4. The direction of electric power can be distinguished automatically, accident is checked automatically. 5. Infrared carrier wave communication and RS485 serial port communication, meter is set up by program and password is protected. |
