ules
Per slot - 1.5 A 0.5 A 8 W for one slot
12 W for both slots
Total - 3 A 1 A
The total power for PCIe cards and USB devices may not exceed 15 W
NOTICE
Device can overheat!
To avoid overheating, the power loss per PCIe slot should not exceed 8 watts.
8.5.4 Integrated DC power supply
Input voltage 24 V DC (-20%/+20%)
Output power of the power supply Max. 80 W
Power failure buffering Hold- up time ≥20 ms with 20.4 V (DC_FAIL is active after > 5
ms)
Efficiency >85 %
Note
Inrush current
The device needs an inrush current of at least 6.5 A for 15 ms.
The peak value of the starting current depends on the input voltage and the impedance of
the 24 V DC power supply. Peak currents greater than 6.5 A are possible. This will not have
a negative impact on device functionality.
