Siemens 6SL3210-1KE22-6UF1 Frequency Inverter

The Siemens 6SL3210-1KE22-6UF1 SINAMICS G120C compact frequency inverter delivers precise three-phase motor speed and torque control for industrial automation and energy-efficient drive systems. With three-phase input 380–480 V AC (+10%/−20%) and 47–63 Hz, it outputs three-phase 400 V AC with 0–550 Hz V/f control, making it suitable for conveyors, pumps, fans, compressors, and machine automation that require accurate speed regulation. Rated power is 11 kW at low overload or 7.5 kW at high overload, and the unit carries a current of roughly 25–33 A depending on load mode, with short-duration overload capability of 150–200%. I/O includes 6 DI, 2 DO, 1 AI, 1 AO, and 1 motor temperature input; communications support PROFINET and Industrial Ethernet; and it provides integrated Safe Torque Off for safety. Its integrated fan cooling and IP20 protection (UL open type), along with compact dimensions about 295 × 140 × 205 mm and weight in the 4.4–5.2 kg range, allow straightforward installation in control panels and OEM machinery.
