Product Introduction
| The Fluke MDA 510 and MDA 550 Motor-Drive Analyzers save time and eliminate the hassle of setting up complex measurements, while simplifying the troubleshooting process for variable frequency drives. 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-500 Series 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-510 and MDA-550 are the ideal portable motor-drive analysis test tools and can help safely locate and troubleshoot typical problems on inverter type motor-drive systems. |
