   Unitariff meters

SEO-1.15D meter

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.

NORMATIVE AND LEGAL BACKING

IEC 62052-11:2003 

TECHNICAL FEATURES

  • The electrical and mechanical reading device or 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.
  • Communication interfaces - optoport (SEO -1.15D.222, SEO -1.15D.222.1, SEO -1.15D.822 meters).
  • The electricity meters have telemetric data output, which ensures transmission of information on the quantity of active energy to a remote data collection system through a two-wire communication line.
  • When manufacturing printing boards, SMD assembling technology is used.
  • SEO-1.15D meter is to be fixed on DIN-bar
