It takes a 600 V DC input and delivers 400 V three-phase AC output at 18 A per channel, with internal air cooling and DRIVE-CLiQ cabling included — a direct swap for a failed unit in a multi-axis line. This module mounts into a SINAMICS S120 chassis, drawing DC-link power from the common bus. The 18 A per channel rating suits dual-motor applications — typically two servo or induction motors on a single module, sharing the same DC bus and cooling. Internal air cooling means it relies on the cabinet's forced airflow; no external heatsink or liquid loop required.","metaTitle":"Siemens 6SL3120-2TE21-8AB0 Double Motor Module, 18 A, Obsole","metaDescription":"Siemens 6SL3120-2TE21-8AB0 SINAMICS Double Motor Module, 600 V DC input, 400 V 3 AC output, 18 A.
