The PS24V25AA power supply units are high-quality switched-mode power supply units for top-hat rail mounting. They impress with their compact and intelligent design as well as their robust metal housing. The output voltage is easy and simple to adjust (22 VDC 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 PS24V25AA power supply units of the same type in parallel.
