The 6SL3120-1TE21-0AA3 is engineered as a booksize single motor module within the Siemens SINAMICS series. It utilizes an air-cooled system to enhance efficiency, providing a cooling air volume rated at 29.6 m³/h. This design allows the module to maintain performance at ambient temperatures up to 40°C, with extended operational capability at 55°C when appropriately derated.

The unit weighs 5 kg and has a rated output current of 9 A RMS, ensuring reliability for most applications. Users will find the base-load capacity set at 7.7 A RMS ideal for continuous operation, while its intermittent duty current reaches 10 A RMS at 40%. For brief, high-load situations, it can endure a peak current of up to 18 A, effectively handling transient demands.

On the technical side, this motor module exhibits a unit rating of 4.8 kW and a power loss of approximately 100.4 W. Its DC-link capacitance is 110 µF, and the maximum DC-link current is noted as 11:00 AM, essential for proper power management. Additionally, the output voltage ranges from 0 to 0.717 times the DC-link voltage, providing flexibility for different operational needs.
