    • It measures key motor-drive parameters, including:
    • Voltage and current (input and output)
    • DC bus voltage and ripple
    • Harmonics
    • Voltage and current unbalance
    • Voltage modulation
    • Motor shaft voltage discharges
  • Comprehensive Measurements:
    • It functions as a 3-in-1 tool: a motor-drive analyzer, a waveform analyzer, and a data logger.
    • It offers extended harmonics measurements to identify the effects of harmonics on electrical power systems.
    • It includes a full 500 MHz oscilloscope, meter, and recording capabilities for a wide range of electrical and electronic measurements.
  • Guided Measurements:
    • It features guided measurement setups with graphical step-by-step connection diagrams, simplifying complex measurements.
    • Preset measurement profiles automate data collection based on selected test procedures.
  • Safety and Durability:
    • It has a high safety rating: 600 V CAT IV/1000 V CAT III, allowing for use at service entrances and downstream.
  • Reporting:
    • It facilitates quick and easy report creation for documenting troubleshooting and collaboration.
  • Harmonic Analysis:
    • It provides the ability to discover the harmonics of the motor-drive, and also discover the possible effects of inverter switching electronics. It has three harmonic ranges, 1st to 51st Harmonics, 1 to 9 kHz and 9 to 150 kHz.
  • Applications:
    • Industrial automation
    • HVAC/R (heating, ventilation, air conditioning, and refrigeration)
    • Motor repair
    • Industrial manufacturing
    • Waste water treatment
    • Oil and gas maintenance.

In essence, the Fluke MDA-550 is a powerful tool for electrical and maintenance professionals who need to diagnose and resolve issues in motor drive systems efficiently and accurately.
