UMG 96-PQ-L-LP, 90-277V

From power quality analysis to energy monitoring, from residual current to temperature monitoring, the UMG 96-PQ-L-LP offers the right functions for every application. Avoid system failures by clearly displaying the entire power quality of a measurement level at low cost with the UMG 96-PQ-L-LP.

Short of space in the switchboard cabinet? Thanks to the low-power current inputs, classic current transformers can be replaced with smaller and less expensive current transformers. Since low-power transformers operate in the millivolt range on the secondary side, no converter disconnect terminal is required.

Passive Rogowski coils can also be used for simple retrofit solutions. In this case, the measurement device serves as the measurement transducer, saving money and essential space in the switchboard cabinet.

The UMG 96-PQ-L-LP modular network analyzer can measure full-wave events and present and analyze them directly in the network display. It also comes with a large memory, which, thanks to a special data compression method, ensures several years’ worth of storage. Memory partitioning preserves the long storage time for current, power and work even in combination with high-resolution power quality measurement.

All values can be conveniently displayed and graphically represented on the color graphic display. What’s more, the UMG 96-PQ-L-LP offers plug-in modules for functional enhancements and 50 comparators that can be configured individually or via predefined comparator profiles.
