INFINITE. FLEXIBLE. BUILT TO GROW.
The UMG 800 Series meets your measurement challenges with flexibility and reliability—today and in the future. Thanks to its modular design, you can adapt the base units at any time to meet changing requirements. Your measurement system grows with you and the challenges you face.
More data, greater transparency
The UMG 800 energy analyser, the UMG 801 power quality analyser and the 800 Series modules bring together a wide range of functions and measurement tasks in a single system. There are suitable modules for every application. For example, users can measure 24 three-phase outgoing feeders plus RCM with a UMG 800 and modules, or analyse power quality with the UMG 801 and modules. The system is scalable and grows with your requirements. New measurements, additional signals and enhanced functions can be integrated at any time.
Room to grow—modular and efficient
Each meter in the series has 13 module slots. Operators can flexibly add functions such as digital inputs or up to 96 current measurement inputs. Depending on the module, it may use no module slots, one slot or several.
Flexible mapping
Virtual meters let operators assign phases to current measurement inputs as needed. This is especially useful for three-phase measurements, as it allows all inputs to be used optimally.
Convenient remote access
The integrated web server lets users access the meters through a browser. Preconfigured dashboards display all live values clearly. Operators can configure the meter directly via the web interface—without any additional software.
Key Features
Flexible expansion
Each base unit can be expanded with modules as needed, until all 13 module slots are filled.
Easy system integration
Using a range of protocols, including OPC UA, Modbus RTU and Modbus TCP/IP, the base units communicate seamlessly with higher-level systems.
Protects your system
In combination with GridVis® software, the UMG 800 series actively monitors limit values and triggers alarms. Modbus whitelisting, secure communication protocols such as OPC UA, and continuous software updates provide long-term stability and security.
Compact and space-saving
The compact DIN-rail design and the narrow profile of most modules save space and make retrofitting easier.
Central data hub
Users can easily connect external data sources, such as meters and sensors, via the Modbus gateway, digital inputs and multifunction inputs. This means the UMG 800 series not only records electrical values, but also serves as a central data hub.
One system for every task
The UMG 800 series supports residual current monitoring, power quality analysis, energy management and load management.
A future-proof foundation
Software updates, modern communication interfaces and modular expansion help protect your investment over the long term.
Precise data for reliable analysis
The system offers high measurement accuracy and detects transients as short as 18 μs. This enables users to analyze energy flows and power quality in detail.
Excellent value for money
Cost-effective expansion modules and flexible mapping of measurement channels deliver an outstanding cost per measurement channel.
Base units

Modular energy analyzer UMG 800
With the UMG 800, you can cost-effectively monitor numerous outgoing circuits and loads. For example, keep track of the energy consumption of your PDUs and gain key figures for energy management in line with ISO 50001.

Modular power quality analyzer UMG 80
The UMG 801 is ideal for precise power quality analysis. It helps you identify irregularities in the power grid and provides a sound basis for assessing your energy supply.
