Product Overview

The 6SL3210-1KE31-4UF1 is a SINAMICS G120C compact AC converter by Siemens, configured for unfiltered (UF) operation and rated at 75 kW nominal power. It converts three-phase 380 - 480 V AC (±10 %/-20 %) input into variable-frequency output suitable for motor control in industrial applications. Located within the G120C compact family, it provides digital and analog I/O, PROFINET/EtherNet-IP connectivity plus Safe Torque Off, making it suitable for machine tools, conveyors, pumps, and general processing equipment. This converter supports overload operation of up to 150 % for 3 s when needed. 6SL3210-1KE31-4UF1.
