Product Description: Siemens 6SL3120-1TE21-0AA3

The Siemens 6SL3120-1TE21-0AA3 is a SINAMICS S120 motor module designed for high-performance servo and vector control applications. Operating on a 3-phase 380–480 V AC input with a continuous output current of 12 A, this module is suitable for dynamic motor control tasks requiring speed, torque, or position accuracy. The booksize format allows for compact side-by- side installation, and the module is used within a common DC bus configuration, typically in modular multi-axis drive systems.
