   Unitariff meters

PSCH-3AR.06

DESIGNATION AND AREA OF APPLICATION

The meter is intended for accounting of active and reactive electric power in three-phase three-, four-wire AC mains with 50 Hz frequency by a single tariff in one or two directions of accounting.
The meter can be used independently or as a part of automated informational and measurement electric power monitoring and accounting systems (AIME PMAS).

ELECTRIC POWER METER TECHNICAL FEATURES

  • The electric power meter has LED indication of current presence in a load circuit, and the frequency of LED dimming is proportional to load power.
  • Possibility of direct or transformer connection.
  • Two electromechanical measuring indicators display the amount of consumed active or reactive energy in kWh or in kilovarh correspondingly with the accuracy of up to decimal (meters of direct connection) or hundredth (meters of transformer connection) fractions.
  • Two telemetric outputs, one for each type of energy.
