Application

DT/SS(X)450 series three-phase electronic combination watt-hour meter 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 reference frequency 50Hz correctly, each technical index of product conforms to requirements for three-phase static watt-hour meters for active and reactive energy stipulated in standards GB/T 17215.321-2008 and GB/T 17882-1999.


Main functions

1. Measurement function: measure active energy and reactive energy.

2. Supplied with three-phase power, any one phaseor 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 failures, its corres-ponding indicator lamp goes out.




Main Technical data

1. Normal working voltage:0.9Un~1.1Un (Un is reference voltage )

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

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

4. Creeping: when voltage circuit voltage is 115%Un,current breaks, 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/T17882-1999.

6. Specified working temperature: -10℃~45℃

7. Utmost working temperature: -25℃~55℃

8. Relative humidity: 25~95%?
