UMG 512

Class A power quality analyser

The Janitza UMG 512 is particularly well suited to the monitoring of power quality in accordance with current standards, e.g. EN 50160, IEEE519 or EN 61000-2-4.

Main features

  • Class A

    Measuring devices in class A are 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 measuring devices reliably record, analyse and document 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. It is already integrated in certain UMG measuring devices. The measuring current transformer that is required can be installed manually at a later date if required. Continuous RCM monitoring increases the system safety and availability significantly. In specific applications such as the data centre, residual current monitoring is essential due to the high availability requirements.

  • 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. The user enters the measuring device IP address in the browser's URL bar and the measuring devices homepage is displayed on the screen. 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

    BACnet is one of the most important communication standards for building technology, mainly due to its compatibility with the most diverse hardware and its uniform communication with devices from various manufacturers. 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.
