Product Overview
The Siemens 6SE6440-2UD13-7AA1 is a MICROMASTER 440 series AC motor inverter (variable frequency drive). It provides continuous motor drive control up to 0.37 kW (0.5 hp), converting three-phase 380-480 V AC supply (±10 %) at 47-63 Hz to a variable-frequency output. Typically it is used in conveyor drives, pumps, fans or small machine tool applications where adjustable speed control of low-power AC motors is required. Practical roles include replacing fixed-speed starters, speed control in manufacturing lines, and energy-saving retrofit upgrades.
