The 6SL3121-1TE32-0AA4 from Siemens is a highly efficient single-motor module classified as a compact booksize unit. It is engineered to deliver impressive performance across various applications. This device handles a continuous load current rated at 141 A (AC RMS) and can sustain a continuous current at a rated load of 200 A (AC RMS).

During short-term duty cycles at 40% load, this module can handle up to 230 A (AC RMS). It is also designed to manage instantaneous currents that peak at a robust 282 A (AC RMS). The output voltage ranges from 0 to 0.717 of the DC-link voltage, ensuring flexibility in operational demands. This motor module operates with a DC-link voltage ranging between 510 V to 720 V DC and boasts a capacitance of 3995 µF.

Control electronics utilize a supply voltage of 24 V DC (with a variation possible between 20.4 V and 28.8 V) while drawing a current of around 0.85 A, reflecting its efficient power management capabilities. The nominal power output rated at 107 kW supports many applications, while the base current power output is 76 kW. Additionally, the module experiences a total power loss of approximately 2070.4 W during operations, indicating its energy efficiency relative to output.

The highest switching frequency achievable without derating is set at 4 kHz, ensuring rapid response times in applications requiring quick operational changes. While the permissible ambient operating temperature can reach 40°C, operations at higher temperatures up to 55°C are possible with a derating, indicating the module's capability to function effectively even in warmer environments.
