The power specifications apply to the power supply component, not to the device.
Note
Differences in power supply performance
A power supply with a maximum continuous output power of 60
W or 80 W can be installed
on the 12", 15" and 19" devices. However, these differences in performance have no
influence on the other properties of the device.
Note
Inrush current
The device needs an inrush current of at least 4.5
A for 25 ms.
The peak value of the
inrush current depends on the input voltage and the impedance of the
24 V source; peak currents in excess of 4.5 A are possible. This will not have a negative
impact on device functionality.
