Output power of 120 watts (5 A)
Overload and overvoltage protection
- Single-phase input: 115/230 VAC
- Output: 24 VDC up to 61 °C
- Output power of 120 watts (5 A)
- Robust metal housing with top-hat rail mounting
The DRAN120-24 power supply units are high-quality switched-mode power supply units for DIN 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 (22.5 VDC to 28.5 VDC) and is highly stable even with temperature fluctuations and load changes.
In addition to short-circuit protection, overload and overvoltage protection at the output also ensure a high level of safety.
