Project Description

A new meter GAMA 300 has been developed for the very rapidly changing electricity market, adapted to deregulation and customers’ growing demands. The electronic electricity meter GAMA 300 operates in three-phase electricity networks and is approved in accordance with IEC 62052-11, IEC 62053-21, IEC 62053-22, IEC 62053-23, EN 50470-1 and EN 50470-3. The electricity meter satisfies the requirements of Directive 2004/22/EC of the European Parliament and of the Council of 31 March 2004 on measuring instruments.

Additionally meter can be equipped with communication modules upon request, allowing easy connection of meters to AMR system directly. The GAMA 300 meter has a changeable (without uninstalling meter from site) Li-ion battery and an internal relay for remote user disconnection.
