SINAMICS S220 booksize module — what the ratings mean
The 6SL5120-1UE32-0AC0: The DC link input range of 495-720 V sets the bus voltage the drive system must supply — this is a higher DC bus than a common 24 V or 48 V industrial supply, so the module sits behind a pre-charge and bus-capacitor stage in the drive cabinet. The 200 A rated three-phase AC output at up to 480 V is what actually drives the servo motor, and at 110 kW rated power this module covers mid-to-large servo axis sizes in packaging, printing, or assembly-line applications. IP20 protection with internal air cooling means the module is intended for a closed cabinet with filtered forced-air circulation — it is not a standalone outdoor or washdown unit. The booksize C form factor (400 × 580 × 320 mm packaging) fits the standard DIN-rail and rack-mount mechanical footprint of the SINAMICS S220 system, so the enclosure must be sized to accommodate the depth and the required airflow clearance specified in the SINAMICS hardware manual. The part is classified under export control ECCN 3A999A, which covers certain industrial servo drives and motor drives above controlled thresholds. Cross-border procurement of this module requires verification against the applicable export regulations for the destination country before shipment — this is not a freely exportable commodity in all jurisdictions.
