29.3 Total current consumption interfaces
The total current consumption at 5 V interfaces must not exceed 5 A:
Every COM* = 300 mA, total of 1000 mA
Every USB2.0/USB3.0 = 500 mA/900 mA, total of 3 A
Every USB (HUB) = 500 mA, total of 2 A
TFT/LCD display
Max. 5 A @ 5 V
The total current consumption at 12 V interfaces must not exceed 5 A:
Every COM* = 600 mA, total of 900 mA
Every PoweredUSB
Every PoweredUSB 12 V*
= 1.5 A, total of 2 A
= max. 3 A
TFT/LCD display
Max. 5 A @ 12 V
The 24 V PoweredUSB interface is provided for the operation of retail thermal printers. The peak load is
configured accordingly. The maximum current strength must not exceed 2 A.
For thermal reasons, the power consumption of additionally implemented PCI and PCIe controllers is limited per
slot to 10W and in total to 20W.
