Overcome Your Power Quality Challenges with Janitza’s UMG 512-Pro

According to a report by Sustainability Outlook titled ‘Energy Management Trends in Indian industry: 2014’, India is expected to face huge energy shortage by 2030, negatively impacting industrial growth and necessitating efforts for energy management.

Given that industry is one of the key energy guzzlers, businesses have a huge role to play in implementing energy management measures to ensure India’s transition towards a resource efficient economy.


Power quality is also a real concern as many electronic devices and automation systems in industrial production plants are sensitive to voltage variations and dips in power supply. Such problems can result in machine downtime, plant shutdowns and production loss. Plus, there’s the risk of non-conformance costs! Therefore, power quality needs to be continuously monitored, measured and analysed to detect unexpected risks before they cause damage.

Amidst growing concerns regarding energy consumption and power quality, and with upcoming legislation from Indian government, Indian industries have to necessarily implement energy management systems that meet high international standards.

For the best power quality monitoring,  power measurement  and analysing, Messung presents Janitza’s UMG 512-PRO – a fixed Class A power quality analyser in compliance with IEC 61000-4-30 Class A and IEEE 519-2014 standards.


The Janitza UMG 512-PRO is particularly well suited to the monitoring of power quality in accordance with current standards, e.g. EN 50160, IEEE 519 or EN 61000-2-4.

Main features

Class A: Certified to the IEC 61000-4-30 standard, it provides detailed specifications that a mains analyser must meet so that the results can also be consulted in case of disputes. The standard defines the necessary parameters, suitable measurement methods, accuracy and bandwidths. This makes it possible to easily reproduce and compare results.

Power quality: Reliable operation of modern plants and systems always demands a high degree of supply reliability and good power quality. UMG 512 PRO reliably records, analyses and documents all interferences such as harmonics, unbalance, transients, voltage dips, voltage swells, flickers, phase shifts and reactive power.

Residual Current Monitoring (RCM): Powerful RCM residual current monitoring already detects leakage currents in their initial stages before they cause system failures or even fires. Continuous RCM monitoring increases the system safety and availability significantly.

Measuring devices homepage: The web server for the measuring device provides a wide range of data in a user-friendly format. The user does not have to install any software on their PC; a conventional web browser is all that is required. In addition to the modern homepage, APPs are available for an extended range of functions.

Ethernet-Modbus-Gateway: The Ethernet Modbus gateway can be used to easily include the Modbus RTU devices that are connected to the master device as slaves in an Ethernet architecture. This is also possible via a Modbus RTU interface for devices with identical file formats and matching function codes.

BACnet: As soon as a UMG measuring device has received its BACnet ID and is integrated into the network, the system recognises it and displays it in the browser. This makes configuration very easy.

GridVis® – network visualisation software

With GridVis®, Janitza offers powerful, user-friendly software for the development of energy and power quality monitoring systems. The basic version GridVis®-Basic, which is part of the scope of delivery of the measurement devices, serves both for the programming and configuration of the UMG 512-PRO and also for the reading out, saving, display, processing and analysis of the measurement data.

GridVis® is a comprehensive and scalable software solution for energy suppliers, industrial applications, facility management, building market and infrastructure projects. GridVis® provides technicians and managers with the required data to identify potential energy savings, reduce energy costs, avoid production shutdowns and optimise the utilisation of production resources.


Janitza’s new PRO series combines the latest technology with excellent functions and attractive design. The increased variety of functions and comprehensive illustration options enable measurement data and measurement results to be analysed and interpreted more easily.

Data can be processed, visualised and analysed with the help of the pre-installed Janitza APPs. APPs are a function extension of the device homepage. The traffic-light principle makes complex power quality analyses, for example, understandable for everyone.

The series includes:

Powerful network analyser with colour graphic display and high degree of userfriendliness. Also, PLC functionality (Jasic), integrated residual current monitoring and comprehensive range of protocols for simple incorporation into existing communication architectures. UMG 509-PRO measures with an accuracy of 0.2 %.

Power analyser for DIN rail mounting with latest communication capabilities (Ethernet, PROFIBUS, Jasic (PLC functionality) and integrated homepage).Comprehensive power quality measurements can be undertaken.

Power quality analyser for DIN rail mounting with standard-compliant power quality measurement per IEC 61000-2-4 and EN 50160. Measurement process implemented in accordance with DIN EN 61000-4-30.
