Product Overview
The Siemens MICROMASTER 440 frequency inverter, model 6SE6440-2AD31-5DA1, is a three-phase variable-frequency drive with internal Class A EMC filter. It accepts 380-480 V AC at 47-63 Hz and provides controlled motor output of 18.5 kW (low-overload) and 15 kW (high-overload). As part of the MICROMASTER 440 platform, it modulates speed via V/f control (up to 650 Hz) and is suited for applications such as pump, fan, and material handling systems in industrial environments. This unit is offered primarily as a spare or replacement drive.
