When a 30 kW fan on a 200-240 V supply runs on PROFIBUS DP, this SINAMICS G120X joins the existing Profibus controller as a native node — 141 A at 110% overload for 60 s, no step-up transformer, IP20 for control-cabinet mounting.

At 30 kW it runs in a 305 x 709 x 369 mm FSF frame. PROFIBUS DP is onboard so no gateway is needed between the drive and the controller. This variant ships without DC terminals, which keeps it lean when the motor cable is short and no external du/dt filter is planned.

For PROFINET or serial/BMS buses the 41482 and 41481 siblings speak those interfaces on the same 30 kW platform. The 41486 sibling adds DC terminals for an external brake resistor or du/dt filter.
