Siemens 6SL3210-1PE14-3UL1 SINAMICS PM240-2 1.5kW/1.1kW 400V IP20 VFD Power Module

The Siemens 6SL3210-1PE14-3UL1 is a SINAMICS PM240-2 power module in frame size FSA, unfiltered with an integrated braking chopper, rated for 380-480 V 3 AC input. It delivers 1.5 kW at low overload (150% for 57 s) or 1.1 kW at high overload (200% for 3 s), requiring a separate Control Unit to operate.

Technical Specifications

Selection Notes

The 1.5 kW low-overload rating suits pumps and fans with light, continuous torque demand, while the 1.1 kW high-overload rating covers applications needing a 200% current spike for 3 s, such as a conveyor start against a loaded belt. Because this is an unfiltered PM240-2, an external EMC filter is required where conducted emissions limits apply; the filtered PM240-2 variant in the same frame size skips that added component. The integrated braking chopper dissipates regenerative energy from decelerating loads directly through a braking resistor without an external braking unit, and the module needs a compatible SINAMICS Control Unit (CU firmware V4.6 or later) to run — it is not a standalone drive.

Applications

Variable speed control of pumps, fans, and conveyors in the 1.1-1.5 kW range on a 380-480 V 3 AC supply, where cabinet space favors the modular PM240-2/Control Unit architecture over a compact all-in-one drive.
