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
