DEM181 Three phase multi-rate AC Kilowatt-Hour Meter |
|
|
DEM181 Three phase multi-rate AC Kilowatt-Hour Meter is used for measuring power consumption in a rated frequency 50Hz three phase three wire or three phase four wire alternating current circuit, which gathers functions of multi-rate (time-of-use) electric energy measuring and max demand electric energy measuring. Its technique performance are completely conform to the stipulated requirement of National Standard GB/T15283-94 and GB/T 15284-2002 and international standard IEC60521.

Functions and features
:
|
1. Infrared remote controller programming setup, message distinguished by code.
2. The message is preserved forever if power is interrupted, inner emplaced spare batteries and are free of maintenance.
3. Have four tariffs, six time zones, twelve daily period of times.
4. The direction of electric power can be distinguished automatically. Any false pulse wouldn’t be input.
5. May choose max demand measuring function.
6. May choose 485 interface and long-distance pulse interface to realize collecting transcription meter.
