Product Information

Full details

The Siemens SITOP PSU100C is a compact, high-efficiency 1-phase stabilized power supply designed for engineers and technicians requiring reliable 24V DC power in space-constrained environments like small control cabinets. Its primary benefit lies in its extremely low idling power losses, making it perfect for machinery that spends significant time in stand-by mode, though its limited 0.6A output capacity means it is best suited for low-power control tasks rather than heavy-duty industrial loads.

Verify that the input voltage matches the 100-230V AC or 110-300V DC specifications and ensure all terminal connections are secure.

Device shuts down during operation

Check if the load exceeds the 0.6A current limit or if a short circuit has occurred on the output side.

Pros and Cons

Pros

  • Extremely compact footprint for tight spaces
  • Energy-efficient with minimal idling power loss
  • Supports both AC and DC input voltages
  • Simple DIN rail mountable design
  • Includes helpful plug-in terminal connectors

Cons

  • Limited to 0.6A output current
  • Not suitable for high-power industrial applications
  • IP20 rating requires enclosure protection against dust and moisture

Setup, Compatibility & Care

Installation of the 6EP1331-5BA00 is straightforward due to its standard rail-mountable chassis. Before mounting, ensure the cabinet provides adequate ventilation to maintain performance within the operating temperature range. Connect input wires (100-230V AC or 110-300V DC) to the designated AC/DC terminals, and attach your 24V load to the output plug-in terminals. Ensure all wires are firmly seated to prevent loose connections. As an IP20-rated device, it must be installed inside an enclosed control box or cabinet to protect against contact, liquids, and debris. Regular maintenance should include periodic inspection of terminal connections for signs of heat or vibration-induced loosening.
