Electronic single-phase energy meters СО-ЭА05, СО-ЭА09, СО-ЭА10, accuracy class 1.0, are designed to record active energy in single-phase double-wire circuits of alternating current of the industrial and domestic consumers, including meters embedded into the automated energy control and record systems.

Meters, type СО-ЭА05 (Singe-element)

co-ea05.jpgMeter СО-ЭА05 is manufactured in 4 options:

  • СО-ЭА05М1 – with and electromechanic counting mechanism;
  • СО-ЭА05Р – with an electromechanic counting mechanism to be installed in the cases of induction meters;
  • СО-ЭА05П – with an electromechanic counting mechanism and a unidirectional IR-port, which ensures reading the data on energy consumption;
  • СО-ЭА5И1 – with LCD display and a unidirectional IR-port, which ensures reading the data on energy consumption.

All modifications of the meters have indicating lights of voltage availability and meter operation, and they are also protected against magnetic field impact and current direction change.

Meters, type СО-ЭА05, are manufactured in accordance with State Standard GOST 30207 and СОУ-Н МПЕ 40.1.35.110:2005, certified for the compliance of the measurement equipment with the approved type, and they have been included into the State register.

Meters, type СО-ЭА09 (Two-element)

co-ea09.jpgMeter СО-ЭА09 is manufactured in 4 options:

  • СО-ЭА09 – with an electromechanic counting mechanism;
  • СО-ЭА09Р – with an electromechanic counting mechanism to be installed in the cases of induction meters;
  • СО-ЭА09П – с electromechanic counting mechanism and a unidirectional IR-port, which ensures reading the data on energy consumption;
  • СО-ЭА09И1 – with LCD display and a unidirectional IR-port, which ensures reading the data on energy consumption.

Meters, type СО-ЭА09, have two elements, which allows to measure energy consumption in the phase and neutral wires.

All modifications of the meters have indicating lights of voltage availability and meter operation, and they are also protected against magnetic field impact and current direction change.

Meters are manufactured in accordance with State Standard GOST 30207 and СОУ-Н МПЕ 40.1.35.110:2005, certified for the compliance of the measurement equipment with the approved type, and they have been included into the State register.

Meters, type СО-ЭА10

co-ea10.jpgMeter СО-ЭА10 is manufactured in 2 options:

  • СО-ЭА10 – maximum current 80 А;
  • СО-ЭА10Д – maximum current 60 А.

Meters meet the requirements of State Standard DSTU IEC 61036:2001, СОУ-Н МПЕ 40.1.35.110:2005 and MEK, have two measurement elements, a bridge for the phase contour and a neutral current transformer, sealed on opposite side of the case by two attached seals during the manufacture. All modifications of the meters have indicating lights of voltage availability and meter operation, indicating signals on wrong meter connection, voltage mains failures at the consumer’s site (equipment-to-ground current leakage or attempt to steal energy).

New structure of the meter provides protection against opening (in break) and the impact of magnetic field on the counting mechanism.
