kwh meter digital 3 phase

Specifications

3 phase kwh meter 

Application

DTS1531 series three-phase electronic watt-hour meter is used for measuring electric energy at three-phase four-wire system and three-phase three-wire system,it adopts digital electric energy measurement chip of high accuracy and wide range ,has obvious features like reasonable structure,stable performance,high reliability,low consumption,long service life,free maintenance and so on,besides,it provides pulse output to take convenience for detecting.

Normal working conditions and installation conditions

1.Specified working temperature:-10°C-45°C ;

2.Utmost working temperature: :-25°C-60°C ;

3.Relative humidity:≤85%(at environment temperature 23°C );

4.There shall be no harmful substance causing the corrosion in the air.

Main Technical data

1.Executive standard :GB/T 17215.3-2008/IEC 61036:2000 and GB/T 17882-1999

2.Class index:class1 and class2

3.Power consumption :less than 2w/10VA;

4.Reference frequency:50Hz

5.Needn't to be corrected after working a long time.

6.Suppied with three-phase power,any one phase or two phase fail ,the watt-hour meter still works normally;

7.Good temperature performance :the error shall not exceed accuracy range within the temperature range :-25°C-55°C ;

8.Good light-load performance ,the instrument has fine accuracy class at ultra-light load;

9.High accuracy of actual online measuring ;

10.Simple installation and operation ;the installation position can't be affected by anything ;

11.Strong ability of transportation resistance;the instrument can't cause the change of error under kinds of normal transportation conditions,user needn't adjust it after opening the box.
