The 6SL3341-7TE41-4AA0 is a SINAMICS S120 Chassis-2 Active Interface Module (AIM) combined with an Active Line Module (ALM) — the front-end power supply and regenerative section for a multi-axis S120 drive system. It takes 380-480 VAC three-phase input and delivers a regulated 510-720 VDC DC-link bus, rated at 1405 A continuous with a 900 kW type rating. This is a Class D product — made to order against customer specifications, requiring engineering services, and not a standard off-the-shelf stocked item. Plan for project-specific lead times and documentation.
This is a Chassis-2 format AIM + ALM — a substantial cabinet-mount assembly, not a DIN-rail snap-on module. It requires a dedicated mounting plate, busbar connections for the 1405 A DC-link, and forced-air cooling clearance. The 510-720 VDC output feeds the shared DC bus for S120 Motor Modules; coordinate the DC-link capacitance and pre-charging sequence with the overall drive system design.
