The Siemens 6SL3136-6AE21-0AA0 is a SINAMICS S120 Smart Line Module, listed as a spare part. It takes a 380-480 V three-phase AC input and delivers a regulated 600 V DC bus at 17 A, good for a 10 kW continuous load. The booksize form factor with cold-plate cooling means it mounts directly to a cabinet back panel or a dedicated heatsink — no fan to clog with mineral dust, which matters in a mill or crusher environment where airborne abrasive fines are the norm. The Control Voltage Adapter is included, so you don't need to order the 24 V power supply module separately.
The 10 kW continuous rating at 600 V DC bus is the number that governs the drive group it can feed. A Smart Line Module is an unregulated regenerative supply — it provides a fixed DC-link voltage to SINAMICS S120 Motor Modules. The 17 A output current sets the limit on how many axes you can hang off this bus: each Motor Module draws its rated DC current, and the sum must stay under 17 A.
Deployment context
The booksize mechanical design and cold-plate cooling make this module suited for sealed or semi-sealed enclosures where fan-driven airflow would pull in conductive dust. It bolts to a flat metal surface that acts as the heat sink; the cabinet wall or a dedicated aluminum plate works.
