More Information

Overview Manuals Applications Protection Efficiency Temperature Range

Features:

  • Accepts a wide 16.8 to 138 V DC operating input range.
  • Delivers regulated 24 V DC at a 2 A rated load.
  • Restarts automatically after an electronically protected output short circuit is cleared.
The ordered module is the DC-input PS 305 execution with 48 W rated output capacity.

It establishes a local 24 V supply for S7-300 and ET 200M electronics in DC-fed cabinets.

Input polarity, earthing, branch protection and total downstream current must be resolved before wiring.

Apter Power can review sourcing, documentation and system matching for 6ES7305-1BA80-0AA0.

  • Battery-backed automation panels can derive a regulated 24 V control rail from the wider station DC bus.
  • Remote I/O cabinets use the supply where AC mains are unavailable but S7-300-compatible loads remain required.
  • Process skids with 48 V or 110 V DC distribution can feed lower-voltage controller and sensor circuits.
  • Electronic output protection limits fault current during a 24 V short circuit.
  • Automatic restart restores the output after the external fault has been removed.
  • IP20 construction requires installation inside a suitable control enclosure.
  • The rated output is 48 W at 24 V DC and 2 A continuous current.
  • Published efficiency is approximately 75% under the specified operating conditions.
  • Cabinet heat calculations must include conversion losses at the expected load.
  • The documented operating range extends from -25 to 70 °C with applicable loading conditions.
  • Ventilation clearances should prevent neighbouring equipment from restricting natural cooling.
  • Temperature assessment must use the actual enclosure ambient rather than room temperature alone.
Description
6ES7305-1BA80-0AA0 converts a 24 to 110 V DC plant supply into a regulated 24 V DC rail rated at 2 A. The wide input range covers battery-backed and industrial DC distribution systems without an upstream AC stage.

Inside an S7-300 or ET 200M cabinet, the module supplies controller and I/O loads that require a stable 24 V source. Electronic short-circuit protection and automatic restart support predictable recovery after temporary output faults.

Load demand, conductor sizing, protective devices and the available DC source must be verified together. The 48 W output limit and temperature-dependent installation conditions apply to the complete cabinet design, not only the nominal voltage match.

Technical notes
Before energizing 6ES7305-1BA80-0AA0, verify DC polarity and keep the connected 24 V load within the 2 A continuous rating.
