An apparatus for controlling and power feeding a number of power-consuming parts, the apparatus comprising a plurality of external units each comprising a power-consuming part, and a safety module, where each external unit comprising means for transmitting to the safety unit information relating to the power required or desired by the power-consuming part of the external unit during a present or future operation thereof. The safety module is adapted to only provide power for those power-consuming parts which totally consume less power than a maximum power consumption limit. This has the advantage that the operation of the parts is not interrupted due to lack of power. A number of schemes of deciding which of the power consuming parts requesting power is to actually receive power. |
