ABSTRACT:
The power adapter (114) has a power input (17, 18) and a power output (117) connected to a plurality of power consumption points (3, 4, 6, 7, 8, 9, 11) and a load-shedding device so designed that, when the consumed power exceeds a predetermined threshold value, the supply of current to at least a predetermined number (7, 8, 11) of power consumption points is interrupted in cascase in a pre-established order until the threshold value is complied with, whereupon the supply of current to these points is then restored in the reverse order. The load-shedding device includes a transmitting circuit for delivering at the power output (117) control signals to which receiving devices (115) are selectively responsive in order to interrupt or restore the supply of current to at least a predetermined number (7, 8, 11) of power consumption points.
