PSCH-4.05.2

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

  • Two or one electrical and mechanical reading device indicates the amount of the consumed electrical energy in kilowatt-hour with the accuracy of up to tenth (PSCH-4.05.2.302) or hundredth (PSCH-4.05.2.301) parts of units.
  • One (PSCH-4.05.2.301) or two (PSCH-4.05.2.302) telemetric outputs.
  • LED indication of the current in the load circuit: the more the load, the more often the LED blinks.
  • Wired via transformer.
