New generation three-phase electricity meter designed for industrial metering. With accuraccy class 0.2s, GAMA 300 measures active and reactive energy and may be single-tariff or multi-tariff.


  • Measurement of active energy (bidirectional), reactive energy (in 4-quadrants) and maximum demand
  • Accuracy class 0.2s (IEC 62053-22)
  • Single or Multi-tariff (up to 6 tariffs)
  • Optical and electrical communication interfaces in accordance with IEC 62056-21 and/or DLMS/COSEM
  • Internal communication modules (USB host, RS485, Ethernet), powering of external modem
  • Internal real time clock
  • Load and billing profiles, instantaneous values
  • The second independent load profile
  • Load profile with phase energy and power values
  • Extended anti-tamper features
  • High-level security (encryption and authentication)
  • Event logbook (power outage, power over-limit, reverse current flow, influence of magnetic field, opening of meter cover, opening of terminal cover, clock setting, parameter change, internal error, firmware update)
  • Power quality monitoring (over-voltage, under-voltage, over-current)
  • Registration of line and transformer losses on the basis of I2h and U2h measurements
