SEB-2.08

PURPOSE AND FIELD OF APPLICATION

    The meter is designed for multitariff accounting of active energy in two-wire power circuits of a.c. with the frequency of 50Hz, independently or as a component of any automated systems for commercial energy accounting

NORMATIVE AND LEGAL BACKING

    IEC 62052-11:2003

TECHNICAL FEATURES

  • Tariff-changing is performed by supplying 12V external control voltage through a two-wire communications line.
  • Two electrical and mechanical reading devices indicate the amount of the consumed power in kilowatt-hour as per each of the tariffs with the accuracy of one hundredth of a unit.
  • Two LED indicators – for a ‘day-time’ (main) and ‘night-time’ (reduced) tariff.
  • Telemetric output.
  • A current transformer or a shunt serves as a current sensor.
  • When manufacturing printing boards, SMD assembling technology is used.
