6SL3120-1TE21-8AC0

The Siemens part number 6SL3120-1TE21-8AC0 is a drive device in the SINAMICS S120 series that is designed for high-performance motor control applications. It has a rated output power of 0.75 kW coupled with an output current of 2.3 A, making it efficient for numerous tasks. Operating within a voltage input range of 380V to 480V AC, this drive matches various industrial electrical systems.

The system features an input current rating of 1.8 A and can handle both 50Hz and 60Hz frequencies, seamlessly transitioning between them. The output frequency can reach 400 Hz, offering flexibility in motor speeds for different applications. Efficiency is a key advantage of this drive, maintaining a rating of ≥ 97%, contributing to overall energy savings.

Cooling is managed through a forced air system, ensuring that the internal components remain within safe operating temperatures. The drive is rated for an operating temperature range of -10°C to +50°C and can be stored at temperatures between -40°C and +70°C..

For added convenience, mounting options include DIN rail and wall mounting, allowing for installation in various configurations. The control methodology incorporates both V/f control and vector control in open or closed-loop modes, enhancing its adaptability to different requirements. The drive also offers an overload capacity of 150% for short durations (60 seconds), allowing for handling unexpected load spikes. An IP20 enclosure rating protects the drive from dust and other foreign bodies while permitting sufficient cooling airflow. Additionally, communication interfaces, including Modbus RTU, Profibus DP, and CANopen, are available for integration into broader systems.
