Item No.: CO5127-1E

Multifunctional power measurement device with mains system analyser, graphic-capable

The measurement device allows for measurement and display of all relevant power system parameters. It can measure and display voltage and current for one, two or three phases, along with the neutral, simultaneously. Display and operation are via menu on a TFT display or via the built-in Ethernet port. The “smart meter” can be used as a digital power meter to measure electricity consumption at the end points of the power grid and to turn consumers on and off depending on circumstances.

Characteristics:

  • Direct measurement up to 690 V, CAT III
  • Class 0.1 (U/I), class 0.2% (P/Q/S), class 0.5 (counter)
  • Power system (mains) condition monitoring
  • Energy consumption analysis (counter, load profiles, trend analysis)
  • Harmonics analysis per IEC 61000-4-7
  • Monitoring of system (mains) asymmetries
  • Limit monitoring with alarm
