PSCH-3.05.2

PURPOSE AND FIELD OF APPLICATION

   The meter is intended for accounting of active electric energy in three-phase, three- or four-wire power circuits of a.c. with the frequency of 50 Hz.
   It can be used either independently or as a component of any information-measuring systems.

NORMATIVE AND LEGAL BACKING

    IEC 62052-11:2003

TECHNICAL FEATURES

  • The electrical and mechanical reading device indicates separately the amount of the consumed electrical energy in kilowatt-hour with the accuracy of up to units or tenth parts of units depending on nominal current.
  • Two telemetric outputs for commercial and technical accounting.
  • Current transformers are used as current sensors.
  • LED indication of the current in the load circuit: the more the load, the more often the LED blinks.
  • When manufacturing printing boards, SMD assembling technology is used.
