Siemens Sinamics S120 6SL3131-7TE21-6AA0 Smart Line Modules

Description

The 6SL3131-7TE21-6AA0 is a SINAMICS S120 active line module designed to provide regulated DC link power from a three-phase industrial AC supply. Manufactured by Siemens, this unit features a 3-phase input voltage range of 380-480 V AC at 50/60 Hz and delivers a regulated 600 V DC output at 27 A with a 16 kW power rating.

The 6SL3131-7TE21-6AA0 utilizes external air cooling to manage thermal dissipation efficiently within cabinet configurations. Each unit includes a Control Voltage Adapter and a DRIVE-CLiQ cable for seamless integration into broader multi-axis drive architectures. The module measures 35.60 x 10.20 x 53.30 cm and weighs 8.60 kg. As a phase-out lifecycle product with a designated successor (6SL3131-7TE21-6AA3), it is deployed primarily to support legacy system maintenance, direct hardware replacement, and operational continuity in established S120 installations.
