The Siemens 6SE6440-2UD17-5AA1 is a variable frequency drive (VFD) engineered for effective control of AC induction motors. It features a power rating of 0.75 kW, proving to be valuable in applications requiring efficient motor management. This drive accepts a three-phase input voltage ranging from 380 to 480 volts, with a tolerance of ±10% around the nominal level.

Its operational input frequency varies between 47 and 63 Hz. The unit offers a constant torque output of 0.75 kW and supports overload conditions, allowing for 150% of the rated current to flow for a duration of 60 seconds. Cooling is achieved through forced air, ensuring optimal thermal management during operation.

Output frequency capabilities extend from 0 to 500 Hz, accommodating different motor speed requirements. An IP20 protection rating indicates that it is suitable for environments that do not involve significant exposure to dust or moisture. The drive operates effectively within an ambient temperature range of -10°C to +50°C and can withstand relative humidity levels between 5% and 95%, provided it remains non-condensing.

Safety is enhanced with built-in overload protection mechanisms for both the drive and motor. In terms of physical dimensions, the VFD measures 173 mm in height, 73 mm in width, and 149 mm in depth, making it a compact choice for various applications.
