DSS(X)1531 THREE PHASE ELECTRONIC COMBINATION WATT-HOUR METERS FOR ACTIVE AND REACTIVE ENERGY

APPLICATION

DSS(X)1531 series three-phase electronic combination watt-hour meters for active and reactive energy adopts ultra-low power consumption large-scale integrative circuit technology as well as SMT technology,it presents high reliability and long service life,can measure active energy and reactive energy at three-phase power grid of referece frequency 50Hz correctly.each tecnical index of product conforms to requirements for three phase static watt-hour meters for active and reactive energy stipulated in standards GB/T17215.321-2008 and GB/T17882-1999.

MAIN FUNCTIONS

1.Measurement function:measure active energy and reactive energy

2.Supplied with three-phase power,any one phase or two phases fail,the accuracy of measurement isn't affected.

3.Output interface:active and reactive and passive pulse output interface with optical coupling isolation

4.Phase failure indication:Three luminescent tubes indicates the phase failure,they represents A phase,B phase,C phase respectively,some phase faiures,its corres-ponding indicator lamp goes out.

MAIN TECHNICAL DATA

1.Normal working voltage:0.9Un-1,1Un(Un is reference voltage)

2.Power consoumption:each voltage circuit power consumption is less than 2W(10VA)

3.Starting current :connected through current transformer,active:0.002ln,reactive:0.003ln;connected directly:active 0.004ln,reactive 0.005ln

4.Creepping:when voltage circuit voltage is115% Un,current breakers,the active and reactive output test pulse shall be not more than one.

5.Error range(%):conform to standards GB/T17215.321-2008  AND GB/T 17882-1999.

6.Specified working temperature:-10°C to +55°C

7.Utmost working temperature:-25°C to +55°C

8.Relative humidity:25%--90%
