Power Module for Liquid-Cooled Drives
The Siemens 6SL3215-1SE31-0UA0 is a SINAMICS S120 Converter Power Module PM340 rated for 3AC 380-480 V input at 50/60 Hz, delivering 3AC 90 A (45 kW) output. The Blocksize FSE frame uses liquid cooling, so this module is designed for a cabinet with a coolant loop — not a fan-cooled standalone unit. The 90 A continuous output at 45 kW means it handles a 55–60 kW motor at moderate overload duty (typical S120 rating practice); verify the motor's full-load amps against the drive's rated output current for the specific application.
Liquid-Cooled Integration Notes
Liquid cooling requires a properly sized coolant circuit (typically deionized water/glycol mix per Siemens guidelines) with the correct flow rate and pressure for the FSE heat sink. The coolant connections are on the module body; verify the hose barb size and sealing before piping. The module mounts on a standard backplate or in a sub-panel — the liquid loop replaces the fan for heat rejection, so the cabinet can be more tightly sealed but the coolant pump and heat exchanger must be accounted for in the system design.
