6SE6440-2UC32-2EA1

The Siemens MICROMASTER 6SE6440-2UC32-2EA1 is a variable frequency drive engineered for efficiency in motor control applications. This VFD has a power rating of 22 kW when providing constant torque and can reach up to 30 kW for variable torque scenarios. The input voltage specifications enable connectivity within a range of 200–240 V AC using a 3-phase configuration, and the device operates efficiently at input frequencies of 47–63 Hz.

The unit is designed to withstand operational demands with an impressive overload capacity, offering 150% for 60 seconds and 200% for a brief duration of 3 seconds. It is mounted as a panel unit with dimensions of 650 mm in height, 275 mm in width, and 245 mm in depth, weighing approximately 20 kg.

Though it incorporates an inbuilt filter, it does not include an additional line filter. The control strategies employed are V/f and vector control, ensuring precise management of motor speed and torque. The device is fan-cooled, promoting effective thermal management during operation.

Suitable applications range across various domains, including pumping systems, air handling fans, conveyor systems, and broader industrial automation uses. Communication within setups is facilitated through RS-485/USS protocol. The VFD represents a versatile option for optimizing motor performance across different industrial settings.
