Product Overview
The Siemens MICROMASTER 440 variable frequency drive, model 6SE6440-2UD31-5DA1, regulates three-phase asynchronous motors. It functions within the MICROMASTER family and provides precise speed and torque control via V/f and sensorless flux vector methods. Designed for integration in drive control loops, it suits industrial systems where adjustable motor drive control is needed-such as pumps, conveyors, compressors, and fans. It accepts 380-480 V AC 3-phase input and delivers up to 15 kW constant torque or 18.5 kW variable torque.
