SINAMICS V20 – Basic Performance Drives | Siemens | 6SL3 210-1KE11-8AF2 6SL3210-1KE11-8AF2 SINAMICS G120C Rated Power

Product Description: Siemens 6SL3210-1KE11-8AF2

The Siemens 6SL3210-1KE11-8AF2 is a compact, entry-level converter from the SINAMICS V20 family, designed for straightforward motor control tasks. Delivering 1.1 kW of continuous output power, it provides reliable speed and torque regulation for standard induction or permanent- magnet motors. With built-in parameter cloning via SD card and an integrated brake-chopper for dynamic deceleration, this V20 model streamlines commissioning and reduces external component requirements. Its rugged IP20 housing, wide supply tolerance, and basic safety integration make it ideal for pumps, fans, conveyors, and simple machine automation.
