Siemens 6SL3210-1SE11-3UA0 | S120 PM340 0.37kW Power Module

The Siemens 6SL3210-1SE11-3UA0 is a single-axis AC/AC converter power module from the SINAMICS S120 drive family. Part of the PM340 Booksize series, this compact unit integrates both rectifier and inverter sections, delivering reliable power conversion for small industrial applications requiring up to 0.37kW of output power.

This module is the smallest power rating in the PM340 lineup, featuring Framesize A (FSA) construction. It is specifically designed for applications where precision matters more than raw power and cabinet space is extremely limited.

Typical Applications for 6SL3210-1SE11-3UA0

This 0.37kW module is ideal for light-duty precision applications:

• Small indexing tables and positioning axes

• Laboratory testing equipment and centrifuges

• Small conveyor belts (under 5 meters)

• Packaging machine feeders and pick-and-place units

• Small fan and pump drives (under 0.37kW motor)

• Medical diagnostic equipment

Why Choose the 0.37kW Model?

If you’re deciding between the 0.37kW (1SE11-3UA0) and the 0.55kW (1SE11-7UA0):

• Choose the 0.37kW if: Your motor is 0.37kW or smaller, torque requirements are under 1.5Nm, and precision control is more important than power headroom.

• Choose the 0.55kW if: You need a small buffer for motor starting currents or plan to upgrade motor size later.

The 0.37kW model offers slightly better efficiency in the 40-80% load range compared to an oversized 0.55kW unit running at half load.

System Compatibility

Compatible with these Siemens control units and software:

• CU310-2 PN (PROFINET)

• CU310-2 DP (PROFIBUS)

• CU320-2 PN (multi-axis, up to 6 axes)

• TIA Portal V15.1 and newer

• STARTER V4.5 and newer

Real-World Installation Tips

Based on customer feedback from installations of this exact model:

• Issue 1: Missing the 24V DC supply - This is the most common support call. The module’s electronics require separate 24V DC. Connect it before applying main power.

• Issue 2: Firmware compatibility - Ensure your CU310-2 firmware is at least V4.7. Older versions may not recognize this module.

• Issue 3: Airflow clearance - Maintain 80mm above and below the module. Stacking modules without this gap causes thermal derating above 35°C ambient.
