Product Overview

The Siemens 6SL3420-1TE21-8AA1 is a Single Motor Module (booksize compact) of the SINAMICS S120 drive family. It functions as a power module providing motor control by converting a DC link voltage (510-720 V) into a three-phase AC output (up to 400 V) with a nominal output current rated at 9 A (base load) and up to 18 A peak. Commonly used in modular drive systems for medium-voltage motor control, it serves in applications such as machine tool drives, packaging systems, and printing presses where precise control and safety functions (SIL 2 / PL d) are required.
