Part identity and key specs
The Siemens 6SL3131-6AE15-0AA1 is a SINAMICS S120 Smart Line Module in the booksize format, delivering 5 kW of regulated DC bus power from a 380-480 V 3-phase AC supply. It outputs 600 V DC at 8.3 A, sized for a multi-axis drive group where the DC link is shared across several motor modules.
What the ratings mean for fit
The 5 kW rating at 600 V DC output tells you the continuous DC bus current it can supply to the motor modules downstream. For a typical SINAMICS S120 booksize cabinet, this Smart Line Module feeds the DC link that powers one or two small servo or spindle drives — think a single 5 kW axis or a group of smaller axes whose total motor power sums to 5 kW. The 8.3 A DC output is the hard limit for the connected load; exceeding it forces the module into current limiting or trips the internal fuse.
Integration and mounting
Booksize construction with external air cooling means this module mounts side-by-side on the standard SINAMICS S120 booksize backplane rail, taking up a single slot width. The external air cooling — a fan mounted on the rear — pulls air through the heatsink fins, so you need clearance behind the panel for airflow. The package includes the Control Voltage Adapter (CVA) and a DRIVE-CLiQ cable, which are required for communication with the Control Unit and for the 24 V control supply. No extra ordering for those two items.
