The Fluke MDA-550 series III motor drive analyzer measures key motor-drive parameters including voltage, current, DC Bus voltage level and AC ripple, voltage and current unbalance and harmonics, voltage modulation, and motor shaft voltage discharges and can also perform extended harmonics measurements to identify the effects of low and high order harmonics on your electrical power system.

The MDA-550 series III is easy to operate. Select a test and the step-by-step guided measurements show the user where to make voltage and current connections, while the preset measurement profiles ensure the user will capture all the data needed for each critical motor-drive section. The MDA-550 series III features a built-in report generator so the user can quickly and easily generate as-found, and as-left reports.
