Janitza UMG 604-PRO - Power Analyzer

Insight into consumption, faults and power quality

Short interruptions, dips, harmonics or a too low mains voltage? They can all lead to high costs. With the Janitza UMG 604-PRO power analyzer, 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.

Power analyzer UMG 604-PRO for a total measurement

On the integrated website of the power analyzer UMG 604-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 UMG 604-PRO power analyzer: 

  • Measuring consumption parameters
  • Measuring power quality parameters such as harmonic to the 40th order
  • Measuring short interruptions, transients and peaks
  • Measuring earth fault currents
  • Measured value generator for building management and automation systems
