Power Quality Analyzer Janitza UMG 512-PRO: insight into consumption, interference and mains voltage quality

Power quality analyzer to prevent problems before they actually arise

With a 5th and 6th current transformer input it is possible to continuously monitor earth fault currents. As a result, a periodic insulation test of your installation is no longer necessary. The Janitza UMG 512-PRO is equipped with a temperature input. Events can also be registered for short-term deviations in frequency and/or reactive power. This makes the analyzer suitable for measuring generators of, for example, emergency power supplies in critical applications.

Power quality analyzer UMG 512-PRO

The Janitza UMG 512-PRO is an all-in-one power quality analyzer and measures the voltage quality according to international standards such as EN 50160, IEEE519 and EN 61000-2-4. Power quality problems are quickly detected, because the quality of voltage and current are automatically reported in accordance with the applicable standards. Voltage dips, peaks and transients that can lead to failure are automatically registered and reported via, for example, e-mail or the web interface. On the integrated website of the power quality analyzer, you immediately see the status of the power quality of your electrical installation. The website is accessible via PC, laptop, tablet and smartphone.

Features of the power quality analyzer UMG 512-PRO:

  • Measuring voltage quality according to IEC61000-4-30, class A
  • Measuring consumption parameters
  • Measuring power quality parameters such as harmonic to the 63rd order
  • Measuring short interruptions, transients and peaks
  • Measuring earth fault currents

Choose the right and suitable energy meter for your application

Fortop Automation & Energy Control has a large number of energy meters in the range. The energy meters differ from each other in the shape, options and type of display. A simple energy meter can meet the short term, but in the longer term a more extensive energy meter is often quickly recouped.
