2TAZ662014R2000 ABB M1M 20 Ethernet Power Meter

Why Choose the ABB M1M 20 Ethernet Power Meter?

The ABB M1M 20 Ethernet is a multifunction panel-mounted power meter designed for electrical-system monitoring, energy measurement and basic power-quality analysis in industrial and commercial installations. As part of the ABB M1M power meter family, it combines essential electrical measurements with Ethernet communication in a compact 96 × 96 mm panel format.

The meter measures voltage, current, frequency, power factor, active power, reactive power, apparent power and energy. It also supports four-quadrant energy measurement for monitoring both consumption and generation, while voltage and current THD measurement provides useful information for assessing harmonic distortion within the electrical network.

Integrated Modbus TCP/IP communication allows measurement data to be incorporated directly into Ethernet-based building-management, energy-management and industrial monitoring systems. The M1M 20 Ethernet uses external 1 A or 5 A current transformers, features an LCD display and operates from a 100–230 V AC/DC auxiliary supply.

Connected Power and Energy Monitoring

The ABB M1M 20 Ethernet brings the principal measurements required for electrical-system supervision into one panel-mounted instrument. Voltage, current, frequency, power factor and active, reactive and apparent power can be monitored locally, while energy measurements provide useful information for consumption analysis, energy management and operating-cost assessment.

Its Modbus TCP/IP interface allows electrical measurements to be transmitted over compatible Ethernet networks without requiring a separate serial communication gateway. Combined with four-quadrant energy measurement and voltage and current THD monitoring, the M1M 20 Ethernet provides a practical solution for connected energy monitoring in commercial and industrial electrical distribution systems.

Typical Applications
