The G3-PLC is a plug and play communication modules designed for smart meters, enabling secure and reliable data exchange between meters and gateways over low-voltage power networks. The module equips with high-performance microcontrollers, ensuring robust communication even under adverse conditions such as overvoltage, phase loss, or neutral disconnection. The module is powered directly by the meter. It complys with G3-PLC standards. The module supports automatic recovery after network disturbances without requiring manual resets, ensuring uninterrupted operation. The module offers flexibility for wide-area smart grid deployments.
