   Unitariff meters

SEO-1.18.402

PURPOSE AND FIELD OF APPLICATION

    The meters are designed for metering of active electrical energy in two-wire power circuits of alternating current with the frequency of 50Hz as well as for transmission of data to the controller’s office of information and measuring system for registration of electric energy consumption through communication lines.

NORMATIVE AND LEGAL BACKING

    IEC 62052-11:2003

TECHNICAL FEATURES

  • The electrical and mechanical reading device 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.
  • For the purpose of using as a component of any automated systems for energy accounting the electricity meters are provided with a pulse output which is galvanically separated from the power network.
  • A shunt is used as a current sensor.
