6SE6440-2UD38-8FA1 SIEMENS - REF

The MICROMASTER 440 6SE6440-2UD38-8FA1 is a high-performance, sensorless vector control inverter designed for a wide range of variable speed applications. This unit operates on a three-phase AC power supply with a voltage range of 380-480V (+10/-10%) and a frequency of 47-63 Hz. It is engineered for constant torque applications, delivering a power output of 90 kW with an overload capacity of 136% for 57 seconds and 160% for 3 seconds. For squared torque applications, it provides a power output of 110 kW. The inverter's dimensions are 1400 mm (height) x 326 mm (width) x 356 mm (depth), and it comes with an IP20 protection rating, making it suitable for installation in environments with minimal exposure to dust and water. It is designed to operate in ambient temperatures ranging from 0 to +40 degrees Celsius. This model does not include an Advanced Operator Panel (AOP) or Basic Operator Panel (BOP). The robust design and advanced control features make it a reliable solution for demanding industrial applications requiring precise motor control and energy efficiency. Its sensorless vector control ensures optimal performance without the need for encoder feedback.
