Fluke MDA-520 Motor Drive Analyzer Repair

Description

Fluke MDA-520 Motor Drive Analyzer Repair

The Fluke MDA-520 is an advanced motor drive analyzer that measures and analyzes variable-frequency-drive (VFD) input and output (voltage, current, V/Hz, modulation, DC bus ripple, harmonics, shaft 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.

FlukeMeterRepair.com repairs and calibrates the Fluke MDA-520 for motor, drive, and predictive-maintenance teams.

Common Fluke MDA-520 problems we fix

• Input-channel damage from VFD harmonics — an input damaged by drive harmonics or transients, repaired.
• Readings out of spec — measurement-circuit drift, recalibrated against standards.
• Acquisition / analysis faults — the analysis engine skewing results, repaired.
• Won’t power on or hold a charge — battery and power faults.
• Display or interface faults.

FAQs

An input or reading on my MDA-520 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.
