- Output: 24 VDC, 14 A up to 60 °C operating temperature
- Flexible output power from 240 watts to 336 watts
- Robust metal housing with top-hat rail mounting
- High overload without shutdown
- 3 different protection modes for the output

The PS24V14AA power supply unit is a high-quality switched-mode power supply unit for top-hat rail mounting. It impresses with its compact and intelligent design and robust metal housing. The output voltage is easy and simple to adjust (22 to 27 VDC) and is highly stable even with temperature fluctuations and load changes. In addition to short-circuit protection with 3 different output protection modes, overload and overvoltage protection at the output and a monitoring relay ensure a high level of safety. The output power can be easily increased by connecting additional PS24V14AA power supply units of the same type in parallel.
