SINAMICS S120 Power Module – 6SL3210-1PE33-7AL0
General Description
The 6SL3210-1PE33-7AL0 is an Active Line Module (ALM) from Siemens' SINAMICS S120 drive system. It serves as a regenerative power supply unit, converting 3-phase AC line voltage into a stabilized DC voltage for the drive system's DC link while enabling energy feedback to the grid.

Key Specifications
Electrical Parameters:

Input Voltage: 380–480V AC (3-phase, 50/60 Hz)

Output DC Link Voltage: 510–720V DC (regulated)

Rated Current: 33A (at 400V input)

Power Rating: ~30 kW (dependent on line voltage and load)

Topology: Active Infineon IGBT-based, with regenerative capability (braking energy can be fed back to the grid).

Cooling & Mechanical:

Cooling Method: 7AL0 → Air-cooled (Liquid-cooled variants use "7UL0").

Frame Size: Likely FS A or FS B (compact design for cabinet integration).

Functional Features:

Active Front End (AFE): Low harmonic distortion (compliant with IEEE 519, EN 61000-3-12).

Regenerative Braking: Recovers energy during deceleration, improving efficiency.

Communication: PROFIBUS/PROFINET (via Control Unit, if attached).

Protections & Compliance:

Overvoltage, undervoltage, overcurrent, and overtemperature protection.

Certifications: CE, UL, cUL (region-dependent).

Typical Applications
Used in SINAMICS S120 multi-axis systems (e.g., CNC machines, printing presses, centrifuges).

Ideal for applications requiring energy regeneration and clean power input.

Notes
For exact derating curves and installation guidelines, refer to the SINAMICS S120 Manual (Siemens Doc-ID: 6SL3097-xxxx).

The "1PE33" in the part number indicates 33A current class and standard line voltage range
