New meter GAMA 300 is developed for a very rapidly changing electricity market, adapted to deregulation and customers' growing demands. Electronic electricity meter GAMA 300 operates in three-phase electricity networks and is approved in accordance with the standards IEC 62052-11, IEC 62053-21, IEC 62053-23, EN 50470-1 and EN 50470-3. 

Meter operates in single-phase electricity networks and independently from current flow direction measure: 

  • Measurement of active energy (bidirectional), reactive energy (in 4-quadrants) and maximum demand
  • Accuracy class 1.0 (B) or 0.5s (C)
  • Measurement in two channels (on phase and neutral lines)
  • Single or Multi-tariff (up to 6 tariffs)
  • Internal real time clock
  • Load and billing profiles, instantaneous values
  • Extended anti-tamper features
  • 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)
  • Optical and electrical communication interfaces in accordance with IEC 62056-21 and/or DLMS/COSEM
  • Internal communication modules (PLC modem, USB host, wireless or wired MBus, RS485, Ethernet), powering of external modem
  • High-level security (encryption and authentication)
  • Internal relay for user disconnection
  • Power quality monitoring (over-voltage, under-voltage, over-current)
  • Measurement of Total Harmonic Distortion (THD)
  • Registration of line and transformer losses on the basis of I2h and U2h measurements
Connection type Three-phase 4-wire or 3-wire
Accuracy class:
-for active energy
