Fluke MDA-550 Motor Drive Analyzer Repair
The Fluke MDA-550 is a motor drive analyzer – it measures the voltage modulation, shaft voltage and dV/dt stress that variable frequency drives inflict on motors.
Is your Fluke MDA-550 worth repairing?
Specialist instruments with limited alternatives, which makes repair the practical route. The drive-specific inputs are the vulnerable part and they are repairable. Our answer for the Fluke MDA-550: Repair. There is little to replace these with. We evaluate free of charge and quote before any work begins, and if the numbers do not favour repair we say so rather than quoting anyway.
What typically fails on the Fluke MDA-550
- Voltage or current channel damage.
- Guided measurement sequences not completing.
- Battery and display faults.
- Report generation faults.
- Shaft voltage input failure – reads as a clean result, which is the worst possible failure mode.
- dV/dt capture faults.
What you get back
