Fluke MDA-550 Motor Drive Analyzer Repair
The Fluke MDA-550 is an advanced motor drive analyzer that measures and analyzes VFD input and output (voltage, current, V/Hz, modulation, DC bus, harmonics, shaft/bearing voltage) to troubleshoot drives and motors. Its accuracy depends on the voltage and current measurement inputs and the acquisition/analysis engine, which is where service and calibration focus.
FlukeServiceCenter.com repairs and calibrates the Fluke MDA-550 for motor-drive technicians, industrial plant managers, and power-quality teams.
Common Fluke MDA-550 problems we fix
- Input-protection restoration — an input damaged by drive harmonics, transients, or an over-range event, repaired.
- ADC / acquisition-board repair — acquisition faults skewing measurements, restored.
- Probe-interface recalibration — voltage or current probe inputs drifting, recalibrated against standards.
- Won’t power on or hold a charge — battery and power faults.
- Display or interface faults.
FAQs
An input or reading on my MDA-550 is off — fixable? Yes. Input and acquisition faults are repairable, then the inputs are recalibrated so drive and motor measurements are accurate, with a NIST-traceable certificate.
Are the inputs verified? Yes — voltage and current inputs are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
