UMG 604-E PRO
More than just a multifunction measurement device. Multifunction measurement device, transients recorder, meter (kWh, kvarh), peak load optimisation, harmonics analyser, PLC, state monitoring, event plotter, data logger.
Harmonics occur due to operating equipment with a non-linear characteristic, e.g. transformers used in saturation, energy saving bulbs, frequency converters and power electronics. They cause a load on the mains due to additional currents and can affect or even destroy operating equipment. This mains feedback can be detected and documented using power quality analysers.
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.
Many UMG measuring devices have their own memory containing typical recording ranges of up to 2 years. Recording is freely configurable. A 128 megabyte memory can record around 5,000,000 values.
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.
Events are short-term increases in voltage, dips in voltage, current swells or short-term interruptions (e.g. through bird strike or short circuits). UMG measuring devices can safely record and process events as of 20 ms and transients as of 50 μs. The causes of power quality variations can be identified and analysed in this way.
The user can use the graphical programming language Jasic® to add their own functions to a UMG measuring device. Up to seven freely configurable user programs can run in parallel, e.g. monitoring processes or notifications when reaching defined threshold values. In addition to the graphical programming option, the user is also free to program the source code directly in JASIC.
Configurable display of current and historical measured values with automatic scaling. Graphical representation on the device's own homepage without additional software installation.
