The Siemens 6SL3100-1AE31-0AB0 is a SINAMICS braking module rated for a 600 VDC input and a peak output of 100 kW for 2 seconds. It sits in the SINAMICS drive family, designed to dissipate regenerative energy from the DC link into an external braking resistor during deceleration or overhauling loads.
The 600 VDC input matches the DC-link voltage of a 400 VAC-class SINAMICS drive (rectified to roughly 540–600 VDC under load). The 100 kW / 2 s peak rating tells you the module can absorb that energy pulse for two seconds — enough for a high-inertia centrifuge or a crane hoist that needs a hard stop, but not a continuous-duty dynamic brake. If your application requires sustained braking beyond 2 s, you need a larger module or a different thermal management strategy.
