The Fluke MDA-550 Series III Motor Drive Analyzer is an all-in-one portable test instrument designed for R&D and maintenance troubleshooting of new energy vehicles, variable frequency industrial equipment, servo drives and energy storage converters. Equipped with guided test workflows and automated measurement routines, it simplifies complex inverter system troubleshooting and delivers repeatable, highly reliable test data.

Preloaded preset measurement profiles support full-link testing covering drive input, DC bus, inverter output and motor assembly. Graphical step-by-step wiring guides eliminate complicated manual setup to capture full parameters including voltage, current, harmonics, shaft discharge voltage and ripple. It integrates three core instruments in one: a 500 MHz oscilloscope, digital multimeter and long-term waveform recorder. The built-in report generator enables one-click export of standardized as-found and as-left maintenance reports.

Boasting the industry’s top safety rating of 600 V CAT IV / 1000 V CAT III, it supports high-voltage harsh tests at facility service entrances. It serves as the core measurement tool for R&D and on-site maintenance of electrification, industrial automation and renewable energy power conversion equipment.
