UMG 96-PQ-L

Whether it's power quality analysis, differential current monitoring or temperature monitoring, the UMG 96-PQ-L offers the right functions for every application. With the UMG 96-PQ-L, it is now possible to cost-effectively provide full power quality transparency at every level, thereby avoiding system failures.

Full-period event measurements can be displayed and analyzed directly on the display. In addition, the modular network offers a large memory that provides several years of storage thanks to a special data compression method.

Storage partitioning allows long-term storage of current and power data, and enables high-resolution power quality measurements to be combined. This method of data storage makes it possible to increase the amount of information stored while keeping hardware costs low.

Available values can be easily displayed and presented graphically on a color display. In addition, the UMG 96-PQ-L offers plug-in modules for functional extensions and 50 configurable comparators that can be customized or use predefined profiles.

S-class versions of the UMG 96-PQ-L offer additional features, including flicker or interharmonic detection, to meet EN 50160 and IEEE519 requirements. It is also possible to activate these features later, even after the device has been purchased.
