The Fluke MDA-550 Series III Motor Drive Analyzer is a comprehensive tool for troubleshooting inverter-type motor-drive systems, combining motor-drive analysis, waveform analysis, and data logging. It measures voltage (1000 V, 1.5% ± 6 counts), current (via clamp, 1.5% + clamp accuracy), DC bus voltage/ripple, harmonics (DC to 51st, 1-150 kHz), voltage/current unbalance, voltage modulation (PWM, dV/dt), and motor shaft voltage to detect bearing-damaging discharges. Guided setups with step-by-step diagrams and preset profiles simplify connections and auto-trigger data capture for drive input, DC bus, output, motor input, and shaft.
The 500 MHz oscilloscope and recorder support advanced diagnostics, while the built-in report generator documents results. Data transfers via USB, WiFi, or FlukeView-2 software. Weighing 2.3 kg, the IP51-rated analyzer is CAT IV 600V/CAT III 1000V, operates in -20 °C to 50 °C, and uses a Li-ion battery (8-hour life). The kit includes three 10:1 voltage probes, three 1400s AC current clamps, a shaft voltage set (brushes, holder, rod, magnetic base), a BP 291 battery, charger, WiFi dongle, FlukeView-2 software, and a roller case. Backed by a three-year warranty, the MDA-550 ensures reliable, repeatable motor-drive diagnostics.
