Four Channel Power Analyzer: LMG450 – by ZES ZIMMER


Multi Channel Power Analyzer

Typical Applications:

Measurements on three-phase motors and drives, power supplies with multiple in/outputs, transformer efficiency and vector groups, easy and accurately power measuring in switchgears, universal meter for power electronic and energy analysis.

  • Four independent current and voltage channels
  • Isolated measurement inputs with extremely low capacitance against earth to assure high dynamics CMR and interference immunity
  • Absolutely gap-free measuring process
  • Harmonic and interharmonic analysis up to the 99th harmonic resp. up to 99 interharmonics
  • Analog und digital in/outputs
  • Additional inputs for current sensors
  • Auto-scaling current sensors compensated in phase and amplitude
  • PC interfaces, memory-card slot, floppy drive
  • Graphical colour display to show 4 to 8 measured values, wave form, diagrams of calculated values, bar charts and vector diagrams (fresnel diagrams)
  • Ergonomic user friendly interface
  • Formula editor
  • LabVIEW driver
