It takes a 380-480 V 3AC, 50/60 Hz input and delivers a 3-phase output rated 178 A, corresponding to 90 kW. The construction is blocksize FSF with liquid cooling. The 178 A output at 90 kW is the continuous motor rating for a 400 V 3-phase induction motor under typical variable-torque load (pump, fan, compressor). Liquid cooling means the module rejects heat to a coolant loop rather than ambient air — critical for sealed cabinets, high ambient temperature zones, or washdown areas where air-cooled fins would be impractical. The FSF blocksize frame determines the mechanical footprint and bus-bar interface; verify the existing mounting plate and DC-link buswork accept an FSF module before ordering. ## Deployment Context This PM340 is the power stage for a SINAMICS S120 drive system, typically paired with a Control Unit (CU) and a Smart Line Module or Active Line Module. It is used in multi-axis machine tools, packaging lines, and process plants where a common DC bus feeds multiple axes. The liquid-cooled variant suits applications with high power density in a small footprint — think extruder drives, high-speed spindles, or marine installations where ambient cooling air is unavailable.","metaTitle":"Siemens 6SL3215-1SE31-8UA0 SINAMICS S120 PM340, 178 A, 90 kW","metaDescription":"Siemens 6SL3215-1SE31-8UA0 SINAMICS S120 PM340 Power Module, 380-480 VAC 3-phase input, 178 A / 90 kW output, liquid-cooled, FSF frame.
