Three-phase input: 340 VAC to 575 VAC
Output: 24 VDC up to 71 °C operating temperature
Output power of 480 watts (20 A)
Overload and overvoltage protection
- Three-phase input: 3 x 340 VAC to 575 VAC
- Output: 24 VDC up to 61 °C
- Output power of 480 watts (20 A)
- Overtemperature and short-circuit protection
- Robust metal housing with top-hat rail mounting
The WRA480-24 power supply unit is a high-quality switched-mode power supply unit for DIN rail mounting. It impresses with its compact and aesthetic design as well as its 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.
