The Siemens 6SL3341-7TE41-3AA0 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 drive system. It takes 380-480 V three-phase AC in and delivers a regulated 510-720 V DC bus, rated at 1260 A continuous, with a type rating of 800 kW.
The product status is Active. The mature lifecycle stage means this is a well-established, production-stable part — no imminent end-of-life signal, but also not a candidate for last-time-buy planning. Export control is straightforward: AL N / ECCN EAR99, so no special licensing for most destinations.
This is a Chassis-2 form factor — a substantial cabinet-mount assembly, not a DIN-rail module. Plan for the physical footprint, bus-bar connections, and forced-air cooling clearance. The AIM + ALM combination handles both the line filter and the active rectification/regeneration in one unit, saving panel space versus separate components. The 1260 A DC bus output feeds downstream Motor Modules. Verify the DC bus capacitance and pre-charge circuit coordination with your total connected load. The regenerative capability means braking energy from decelerating axes is returned to the line, not dumped as heat — a key efficiency gain for high-inertia or frequent-cycling applications.
