Product Overview

The Siemens 6SL3330-1TE35-3AA3 is a heavy-duty Basic Line Module (BLM) belonging to the SINAMICS S120 modular drive system. This chassis-format power unit serves as the primary infeed for multi-axis drive configurations, converting three-phase AC line voltage into a stable DC link supply. Rated at 250 kW, it is designed to feed multiple motor modules, providing a centralized and efficient power source for complex motion control tasks. By utilizing a non-regulated infeed principle, this module offers a robust and cost-effective solution for industrial plants that do not require regenerative braking energy to be fed back into the grid.
