Features:

  • Designed for the SINAMICS G120 Modular Drive System
  • Provides Variable Frequency Motor Control with Integrated Braking Chopper
  • Supports High Overload and Low Overload Industrial Applications
The SIEMENS 6SL3210-1PE21-4UL0 Power Module functions as a PM240-2 Power Module within the SINAMICS G120 drive platform, providing efficient power conversion and motor control for three-phase AC motors. Operating with a 380–480 VAC, 47–63 Hz power supply, the 6SL3210-1PE21-4UL0 Power Module delivers reliable variable frequency output while incorporating an integrated braking chopper for applications requiring controlled deceleration. Designed without an internal EMC line filter, the 6SL3210-1PE21-4UL0 Power Module allows users to select suitable external filtering solutions according to installation requirements.

The SIEMENS 6SL3210-1PE21-4UL0 Power Module serves as the primary power stage of a SINAMICS G120 drive system and operates together with compatible SINAMICS Control Units such as the CU240E-2 or CU250S-2. As a modular drive component, the 6SL3210-1PE21-4UL0 Power Module provides dependable speed regulation, stable torque output, and overload capability for industrial equipment including conveyors, pumps, fans, compressors, and material handling systems. Its compact FSB frame and forced-air cooling design allow straightforward installation within standard industrial control cabinets.

For complete drive operation, the 6SL3210-1PE21-4UL0 Power Module must be combined with a compatible SINAMICS G120 Control Unit and commissioned through an optional operator panel or engineering software. The integrated braking chopper enables connection to an external braking resistor when regenerative braking is required, while an external EMC line filter can be installed where electromagnetic compatibility regulations apply.

The 6SL3210-1PE21-4UL0 SIEMENS Power Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
