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.
