Siemens 6SL3210-1SE11-7UA0 | S120 PM340 0.55kW Power Module

Product Overview
The Siemens 6SL3210-1SE11-7UA0 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 light industrial applications requiring up to 0.55kW of output power.

This module sits between the 0.37kW and 0.75kW variants, offering a balanced solution for applications that need a small power buffer without jumping to the next frame size. It features a three-phase input design operating on 280-480V AC.

Typical Applications for 6SL3210-1SE11-7UA0

This 0.55kW module is well-suited for:

• Small conveyor systems (5-10 meters)

• Labelling machines and capping stations

• Small pumps and fans (0.55kW motors)

• Light assembly line positioning axes

• Material handling equipment for light loads

Why Choose the 0.55kW Model?

The 6SL3210-1SE11-7UA0 offers a sweet spot for many light industrial applications:

• Better than 0.37kW: Provides headroom for motor starting currents and small load variations

• More cost-effective than 0.75kW: Lower initial investment when you don‘t need the extra power

• Same footprint: Uses the same compact form factor as the 0.37kW model

System Compatibility

Compatible with:

• CU310-2 PN (PROFINET)

• CU310-2 DP (PROFIBUS)

• CU320-2 PN (multi-axis setups)

• TIA Portal engineering platform

• STARTER / SCOUT software

Real-World Installation Tips

• Altitude derating: Above 1000m, reduce rated current by 5% per 500m elevation.

• Humidity considerations: The module operates reliably up to 80% RH non-condensing, but avoid direct moisture exposure.

• Cable length: Maintain motor cable lengths under 50m for shielded cables to prevent EMI issues.

Comparison with Adjacent Models

Frequently Asked Questions

Q: What voltage range does 6SL3210-1SE11-7UA0 support?
A: The module supports an input voltage range of 280-480V AC, three-phase. This is actually wider than the standard 380-480V range found on other models, offering better tolerance for voltage fluctuations.

Q: What is the weight of this module?
A: The module weighs approximately 0.54 kg (1.19 lbs), making it one of the lightest in the PM340 series.

Q: Can this module operate at high altitude?
A: Yes, up to 1000m without derating. Above 1000m, derating is required (5% current reduction per 500m).

Q: Is this an original Siemens product?
A: Yes. 100% genuine with full manufacturer warranty.
