3.6 KTUS15 Power
3.6.1 Power Budget
The KTUS15 has several outlets for supplying power to external devices. Each power rail is independent of
other power rails, and the power budget for a single power rail can be shared among the interfaces that
utilize it. The maximum load for each rail should however not be exceeded, hence it is not possible to apply
full load to all external interfaces at the same time. The total power budgets for the individual rails are listed
below. Power output pins for the interfaces can be found in chapter 4.

3.6.2 Power Consumption
The KTUS15/mITX board is powered through the PWR connector by a single supply DC voltage.

Notes:
The onboard PSU efficiency varies depending on actual load, input voltage and temperature.
The above mentioned power consumptions are typical values and varies ~+/- 25% from system to system.
