Fluke MDA-550 Series III Motor Drive Analyser

The Fluke MDA 550 Series III Motor-Drive Analyser saves time and eliminates the hassle of setting up complex measurements, while simplifying motor-drive troubleshooting. Simply select a test and the step-by-step guided measurements show you where to make voltage and current connections, while the preset measurement profiles ensure you will capture all the data you need for each critical motor-drive section-from the input to the output, the DC bus, and the motor itself. From basic to advanced measurements, the MDA-550 has you covered, and with a built-in report generator you can quickly and easily generate as-found, and as-left reports with confidence. The MDA-550 is the ideal portable motor-drive analysis test tool and can help safely locate and troubleshoot typical problems on inverter type motor-drive systems. FEATURES Guided testing with graphical step-by-step connection diagrams. Preset measurement profiles reduce setup complexity. Built-in report writing capabilities.
