What this part is and what it does
The Siemens 6SL3130-7TE31-2AB0 is a SINAMICS S120 Active Line Module — the front-end power supply that takes three-phase 380-480 V AC and regulates it to a 600 V DC bus for the drive system. Rated at 200 A DC output and 120 kW, it's the module that feeds the motor modules downstream. It ships with the Control Voltage Adapter and the DRIVE-CLiQ cable pre-installed, which saves a couple of wiring steps during commissioning.
What the ratings mean for fit
The 200 A DC output at 600 V DC is the bus rating the module can sustain. That 120 kW figure is the continuous power it can deliver to the DC link — sized for a multi-axis drive group where the total motor power doesn't exceed that limit. The 380-480 V three-phase input range covers standard European and North American line voltages; the 50/60 Hz tolerance means it works on either frequency without derating. Internal air cooling keeps the enclosure simple — no external water or fan pack needed, just clear space around the module for airflow.
Where it fits in the panel
This is a SINAMICS S120 booksize or chassis format module — it mounts in a standard Siemens S120 lineup alongside the Control Unit and Motor Modules. The DRIVE-CLiQ cable connects it to the Control Unit for communication and DC-link regulation. Panel builders need to account for the internal air cooling: the module draws air through its heatsink, so clearance above and below is required per the mounting guidelines. The Control Voltage Adapter is already included, so no separate 24 V supply module is needed for the electronics.
