DTS(X),DSS(X)1977 Type Electronic three-Phase active and reactive composite watt-hour meter
PURPOSE AND APPLICABLE SCOPE
DTS ( X ),DSS ( X )1977 type three-phase three wire / three-phase four-wire electronic active and reactive composlte watt -hour meter is adopted to three-phase double direction power electric energy measurement special IC/SMT manufacture technology , it can measure rated fequency 50Hz of three-phase active and reactive electric energy lts performance is inconformity with " GB/T 17215.321-2008 " , " GB/T 17215.323-2008 " .
The ambient temperature is-30 ºC~55 ºC ,the relative humidity is not over 85%.
FUNCTION AND FEATURE
1.0 class three-phase three-wire / three-phase four-wire active electric energy measurement .
2.0 class three-phase three-wire / three-phase four-wtre reactive electric energy measurement-Active ,reactive power pulse output independently.
Active ,reactive electric energy has two machines registers.
90° sine reactive electric energy measurement , to guarantee that the accuracy of measurement of reactivee electric energy when unbalance load.
Active ,reactive electric energy double direction measurement.
H igh accuracy ,high reliability ,low power consumption.
The wide working temperature range.
Need not to calibrate for Iong-term working.
