SINAMICS V20 – Basic Performance Drives | Siemens | 6SL3 210-1KE12-3UF2 6SL3210-1KE12-3UF2 SINAMICS G120C Rated Power

Product Description: Siemens 6SL3210-1KE12-3UF2

The Siemens 6SL3210-1KE12-3UF2 is a mid-range converter in the SINAMICS V20 family, offering straightforward motor control for general- purpose applications. Delivering 1.5 kW of continuous power, it provides reliable speed and torque regulation for standard induction or permanent- magnet motors. Featuring an onboard keypad, SD-card parameter cloning, and an integrated brake-chopper for dynamic braking, this V20 variant simplifies commissioning and reduces external component needs. Its rugged IP20 housing, wide voltage tolerance, and basic safety integration make it ideal for pumps, fans, conveyors, and light machinery.
