1. A power supply control device for permitting energisation of a plurality of electrical devices from a single mains supply electrical outlet characterized in that there are provided a plurality of controlled electrical outlets;
- a single electrical input adapted to connect to a mains supply electrical output;
switch means adapted to connect an electrical supply from the mains supply electrical outlet to each of the controlled electrical outlets in response to a functional state of a master electrical device, a state sensor adapted to detect a the functional state of the master electrical device, said sensor being adapted to distinguish at least two functional states of the master device by sensing the value of current flow through and voltage across the master device for calculation of the power consumption of the master device.

Abstract
The present invention discloses a power supply control device to which can be attached a number of electrical device(s), such as a computer or AV equipment. The power supply device is able to determine and monitor standby power usage levels of the device(s) so that when the control device detects that the connected electrical device(s) are not being used power supply is removed from the device(s).
