6SL3120-1TE21-8AA4 SIEMENS Redundant Power Supply Module -20...55 °C (-4...131 °F)

6SL3120-1TE21-8AA4 SIEMENS Redundant Power Supply Module -20...55 °C (-4...131 °F)

• High Power Density & Compact Design:​ The module is engineered for maximum performance in a minimal space, allowing for efficient cabinet layout in complex, multi-drive systems.
• Modular & Scalable:​ As part of the SINAMICS S120 system, it allows for building centralized or decentralized drive topologies, sharing common DC link and control components for optimized system cost and performance.
• Vector Control for High Dynamic Response:​ Delivers outstanding speed and torque control accuracy, enabling precise positioning, rapid acceleration/deceleration, and high overload capacity for complex motion profiles.
• Integrated Safety Functions (via external technology):​ When combined with a Siemens Control Unit (e.g., CU320-2), the S120 system can implement integrated safety functions like Safe Torque Off (STO) as per SINAMICS Integrated Safety, reducing the need for external safety relays.
• Excellent Connectivity & Diagnostics:​ Easy integration via PROFIBUS or PROFINET interfaces (through the associated Control Unit) and comprehensive diagnostic capabilities via status LEDs and the Siemens engineering software (STARTER or TIA Portal).
• High Reliability & Durability:​ Built with industrial-grade components and features extensive protection mechanisms (overcurrent, overvoltage, overtemperature) for reliable operation in harsh industrial environments.

• Material:​ The module casing is made of sturdy sheet metal for electromagnetic compatibility (EMC) and mechanical protection. The power section utilizes high-performance Insulated-Gate Bipolar Transistors (IGBTs), a robust heatsink for thermal management, and high-quality electronic components on a durable printed circuit board.
• Primary Applications:​ Ideal for high-performance, multi-motor applications. Key uses include:
  • Machine Tools (spindle and feed drives)
  • Printing and Packaging Machinery
  • Material Handling Systems (conveyors, cranes)
  • Test Benches
  • Film and Fiber Production Lines
  • Centrifuges and Pumps
