PURPOSE AND FIELD OF APPLICATION

    The meters are intended for metering of active electrical energy in two-wire power circuits of alternating current with the frequency of 50Hz.

    The data on power consumption is indicated on the liquid-crystal display or on the electrical and mechanical reading device which is protected from electromagnetic influences. Due to telemetric data output of the meters they can be used as a component of any automated systems for commercial energy accounting.

NORMATIVE AND LEGAL BACKING

    IEC 62052-11:2003

TECHNICAL FEATURES

  • The electrical and mechanical reading device or the liquid-crystal display indicates the amount of the consumed power in kilowatt-hour with the accuracy of one hundredth of a unit.
  • LED indication of the current in the load circuit: the more the load, the more often the LED blinks.
  • Reading devices with the reverse motion lock and protection from electromagnetic influences are used in the electricity meters.
  • The electricity meters are provided with a pulse output, which is galvanically separated from the network and ensures transmission of information on the quantity of active energy to a remote data collection system through a two-wire communication line.
