Why Choose the ABB D1M 20 Modbus Power Meter?
The ABB D1M 20 Modbus is a compact and highly capable DIN rail power meter and network analyser designed for detailed monitoring of electrical distribution systems. As part of the ABB D1M power meter series, it measures voltage, current, frequency, power factor, active, reactive and apparent power and energy, providing comprehensive electrical data for energy-efficiency and system-monitoring applications.
The D1M 20 extends standard energy monitoring with power-quality analysis, including voltage and current Total Harmonic Distortion (THD) and measurement of individual harmonics up to the 40th order. It supports single- and three-phase systems, balanced or unbalanced loads and four-quadrant measurement for both consumed and generated energy.
With 1 A and 5 A current-transformer inputs, voltage measurement up to 300 V AC, an 85–265 V AC/DC auxiliary supply and integrated Modbus RTU communication over RS-485, the D1M 20 Modbus is ideal for connected switchboards and energy-management systems. Two digital inputs and two digital outputs further enhance integration with external equipment and automation systems.

Comprehensive Electrical and Power-Quality Monitoring
Multifunction power meters such as the ABB D1M 20 Modbus provide substantially more information than basic energy meters. In addition to accumulated energy, the meter monitors voltage, current, frequency, power factor and active, reactive and apparent power, allowing operators to assess electrical loading, energy consumption and operating conditions throughout a distribution system.
The D1M 20 also provides power-quality information through voltage and current THD and individual harmonic measurement up to the 40th order. Combined with Modbus RTU communication, these measurements can be transferred to compatible energy-management, supervisory and automation systems for centralised analysis and monitoring.
Typical Applications
- Industrial electrical distribution monitoring.
- Commercial building energy-management systems.
- LV and MV electrical network monitoring.
- Switchboards and electrical distribution panels.
- Machine and equipment energy monitoring.
- Power-quality and harmonic analysis.
- Energy-efficiency and consumption monitoring.
- Remote monitoring through Modbus RTU networks.
