Janitza UMG 605-PRO - Power Quality Analyzer

Insight into consumption, faults and mains voltage quality

Short interruptions, dips, harmonics or a too low mains voltage? They can all lead to high costs. With the UMG 605-PRO network analyzer from Janitza, these can all be recognized and forwarded via e-mail or SMS. The meter is a PQ analyzer, kWh meter with 8 rates, IP gateway, logger, PLC and web server in one housing.

Janitza UMG 605-PRO for a total measurement

On the integrated website of the UMG 605-PRO you immediately see the status of the power quality of your electrical installation. The website is accessible via PC, laptop, tablet and smartphone. By being able to automatically report the quality of voltage and current according to the applicable standards, power quality problems are quickly detected. Partly due to the integrated temperature measurement, this all-rounder is the ideal analyzer for a 'total measurement' on the low-voltage side of your power transformer.

Features of the power quality analyzer UMG 605-PRO: 

  • Measuring voltage quality according to IEC61000-4-30, according to 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.
