   Unitariff meters

PSCH-3R.05.2

PURPOSE AND FIELD OF APPLICATION

    The meter is intended for accounting of active and reactive electric energy of direct connection in three-phase, three- or four-wire power circuits of a.c. with the frequency of 50 Hz (of the forward direction).

    The meters can be used either independently or as a component of any automated  information-measuring systems for commercial energy accounting (AIISKUE).

NORMATIVE AND LEGAL BACKING

    IEC 62052-11:2003

TECHNICAL FEATURES

  • A liquid-crystal display or a two electrical and mechanical reading devices indicate  the amount of the consumed active and reactive electrical energy.
  • Two telemetric outputs: one for each kind of energy.
  • LED indication of the current in the load circuit: the more the load, the more often the LED blinks.
  • Communication interface - optical interface (PSCH-3R.05.121).
