SIEMENS 6SL3352-1AE37-5BA1 – High-Power AC Drive Power Module | SINAMICS S120 Platform
Engineering Background
The SINAMICS S120 platform represents Siemens’ flagship modular drive architecture, engineered for demanding multi-axis and single-axis motion control applications across heavy industry, process automation, and precision manufacturing. The S120 system separates the Control Unit from the Power Module, enabling flexible topology design and centralized control of multiple axes from a single controller.
Product Positioning
The 6SL3352-1AE37-5BA1 is a high-power Booksize Power Module within the SINAMICS S120 family, designed to deliver regulated DC bus power to connected Motor Modules. It is the preferred choice for procurement engineers specifying drives in steel, paper, mining, marine, and large-scale OEM machine tool applications where power density, reliability, and Siemens ecosystem integration are non-negotiable.

System Architecture & Signal Flow
The 6SL3352-1AE37-5BA1 operates as the power backbone of an S120 Booksize drive line-up:
- Mains Input → Line filter (external) → Line reactor (external) → ALM input terminals
- ALM (this module) → Rectifies and actively regulates DC bus voltage
- DC Bus → Distributed to S120 Motor Modules (Single-Axis or Double-Axis)
- Control Unit (CU320-2 / CU310-2) → Communicates with ALM and all Motor Modules via DRIVE-CLiQ daisy chain
- SIMATIC PLC → Issues motion commands via PROFINET/PROFIBUS to Control Unit
Note: External line reactor and EMC filter are required for CE-compliant installation. Consult Siemens SINAMICS S120 System Manual (6SL3097-4AA00-0BP6) for wiring diagrams.
