The SINAMICS G120X 6SL3230-3YE28-0UB0 is a 15 kW frequency converter in the FSC frame size, configured with an unfiltered output stage and an IOP-2 operator panel. It is designed for pump, fan, and compressor applications in water/wastewater, building technology, and HVAC sectors requiring reliable variable-speed control at 380–480 V 3 AC.

What does the 0UB0 suffix configuration include?

The suffix 0UB0 decodes as: no DC terminals (0), unfiltered output with no integrated EMC filter (U), and full-feature configuration with IOP-2 graphical operator panel (B). The unfiltered output means external EMC measures must be applied where conducted emissions compliance is required. The IOP-2 panel provides a local graphical interface for commissioning, parameterization, and diagnostics at the drive.

How does the unfiltered variant compare to the C2 EMC variant?

At the same 15 kW power rating with IOP-2 and no DC terminals, the 0UB0 (unfiltered) omits the integrated Category C2 EMC filter included on the 0AB0. The C2-filtered variant provides built-in conducted emissions compliance for industrial environments; the unfiltered variant requires the user to supply external filtering if EMC compliance is needed. The choice depends on whether the installation already includes system-level EMC measures.
