The Siemens 6SL3330-7TH35-8AA0 is a SINAMICS Active Line Module rated for a 3AC 660-690V supply at 50/60Hz, delivering 575A output into a DC link of 890-1035V and a rated power of 560kW. This is the front-end converter that regulates the DC bus voltage and shapes the input current for a multi-axis drive system — it's not a standalone inverter, but the power supply for the common DC bus that feeds downstream motor modules.
Chassis unit with IP00 protection and internal air cooling — it's designed for an enclosed cabinet with forced ventilation, not standalone outdoor or washdown duty. The DRIVE-CLiQ cable is included, which simplifies commissioning on a SINAMICS S120 common-bus system: one cable carries both the communication and the 24V supply for the electronics, so the module self-identifies to the Control Unit on power-up.
At 560kW and 575A on a 660-690V line, this module is sized for large multi-axis applications — think high-power conveyor drives, extruder lines, or test stands where several motors share a regulated DC bus. The active front end (AFE) topology means it regenerates braking energy back to the line and draws a sinusoidal current with low harmonics, which can save on upstream filtering and comply with IEEE 519 without a separate active filter.
