The permissible total power for PCIe and USB cards may not exceed max. 15 W
Note
Device can overheat!
To avoid overheating, the power loss per PCIe slot should not exceed 8 watts.
8.4.4
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
At least 5 A inrush current for 15 ms is required for device startup.
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.
8.4.5
AC voltage supply
Input voltage
100 - 240 V AC (-15% / +10%); 50 - 60 Hz
Output power of the power supply
Max. 80 W
Power failure buffering
"AC FAIL" becomes active after >= 20 ms,
The power supply continues to buffer for >= 20 ms at >= 93 V
Efficiency
>85 %
Note
Inrush current
The power consumption of the device is dependent on the device configuration and can be
up to 1.1 A.
The peak value of the starting current depends on the input voltage and the impedance of
the power supply, and can be up to 50 A for < 1 ms. This will not have a negative impact on
device functionality.
