Active Line Module for SINAMICS S120 drives
The Siemens 6SL3130-7TE31-2AA1 is a SINAMICS S120 Active Line Module, listed as a spare part. It takes a 380-480 V three-phase AC input at 50/60 Hz and delivers a regulated 600 V DC bus at 200 A, supporting a power rating of 120 kW. Internal air cooling handles the thermal load, and the module ships with the Control Voltage Adapter and a DRIVE-CLiQ cable — meaning you don't need to order those separately for commissioning. This is the regenerative-capable front end for a multi-axis S120 drive group. The 600 V DC output feeds the DC link common to several Motor Modules; the 200 A rating sets the total current budget for all connected axes. Sizing the line module correctly for the sum of motor currents avoids DC-link sag under load.
Lifecycle and sourcing reality
For a BOM line that needs this exact order code, the mature status gives confidence that the part is still available through normal Siemens distribution channels. We source and quote it to order against an RFQ; availability and current pricing are confirmed at quote time.
Integration notes for the panel builder
The module uses internal air cooling — no external fan or coolant plumbing required, but the enclosure must allow free convection or forced airflow around the heatsink. Mount it with clearance above and below for vertical airflow; stacking other heat-generating gear directly adjacent will reduce the thermal headroom. The included DRIVE-CLiQ cable connects the line module to the S120 Control Unit for communication and feedback. The Control Voltage Adapter supplies the 24 V DC electronics power from the DC bus or an external source — verify the adapter's input range matches your auxiliary supply before wiring.
