Why Choose the ABB D1M 20 Ethernet Power Meter?
The ABB D1M 20 Ethernet is a compact and advanced DIN rail multifunction power meter designed for comprehensive electrical measurement, energy monitoring and basic power quality analysis in industrial and commercial distribution systems. As part of the ABB D1M power meter series, it combines extensive measurement functionality with Ethernet connectivity in a space-saving three-module housing.
The D1M 20 measures voltage, current, frequency, power, power factor and active, reactive and apparent energy. It supports four-quadrant energy measurement for consumption and generation, while advanced power-quality functions include current and voltage Total Harmonic Distortion (THD), individual harmonics up to the 40th order and electrical unbalance measurement.
This Ethernet version incorporates Modbus TCP/IP communication via RJ45, enabling straightforward integration with compatible building management, energy management and industrial monitoring systems. Current measurement is CT connected using 1 A or 5 A current-transformer secondaries, with a maximum meter current of 6 A, while its auxiliary supply accepts 85–265 V AC/DC.
