Fluke MDA-510 and MDA-550
The Fluke MDA-510 and MDA-550 Motor Drive Analyzers are portable tools designed for safe and efficient troubleshooting of inverter-type motor-drive systems. These analyzers streamline the process of identifying common issues by simplifying complex measurements and reducing setup time. The step-by-step guided instructions direct users on where to connect voltage and current probes, while pre-configured measurement profiles ensure comprehensive data collection for each critical section of the motor-drive system, from input to output, including the DC bus and the motor itself. With the MDA-500 Series, you'll be equipped for both basic and advanced measurements, and the built-in report generator makes it easy to create detailed as-found and as-left reports with confidence.
