  Auxiliary Power Supply Modules supply the auxiliary power supply for the SINAMICS S120 Cabinet Modules. Units connected to this auxiliary power supply system include the fans of the SINAMICS S120 devices installed in the Cabinet Modules. In addition, the auxiliary power supply system supplies the electronic modules with an external voltage of 24 V DC. This is required when the DC link is not charged, for instance, in order to maintain PROFIBUS/PROFINET communication.

  Дизайн

  The Auxiliary Power Supply Module is connected in the customer's plant to a voltage corresponding to the respective rated unit voltage.

  The standard version contains the following components:

  • Fuse switch disconnector with fuse monitoring for external evaluation
  • Supply of the auxiliary power supply system with 3 fused auxiliary voltages:
    • 24 V DC for the electronics power supply
    • 230 V 2 AC to supply 230 V loads
    • 380 V to 690 V 2 AC to supply the equipment fans
  • Transformer with 230 V output voltage
  • SITOP 24 V DC power supply
  • 6-pole auxiliary power supply system (ready-wired), including connections for looping through to the next Cabinet Module
  • Nickel-plated PE busbar (60 mm × 10 mm), including jumper for looping through to the next Cabinet Module
