The ABB M1M DS-05 is a digital dual-source electrical meter designed for monitoring and comparing electrical parameters from two independent power supplies. It is suitable for installations where power is supplied by utility mains and a backup generator, allowing operators to monitor source conditions from a single metering device.

The meter belongs to ABB's M1M panel-meter portfolio and provides Class 0.5 measurement accuracy. It is intended for electrical distribution panels, generator control panels, and industrial power monitoring applications. This model does not include built-in Modbus RTU/RS-485 communication; a separate Modbus-enabled version is available for systems requiring remote monitoring or integration with automation platforms.
