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).
Claims27
A power supply control device characterized in that there are provided:
- a plurality of controlled electrical outlets;
- a single electrical input adapted to connect to a supply electrical outlet;
- switch means adapted to connect an electrical supply from the 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, said sensor comprising a current-sensing element adapted to sense the value of current flow through the master device and a voltage-sensing element adapted to separately sense voltage across the master device for calculation of the power consumption of the master device.

- a single electrical input adapted to connect to a supply electrical outlet;
- a power sensor comprising a current-sensing element adapted to detect current flow through a master electrical device and a voltage-sensing element adapted to separately sense voltage across a master electrical device to detect power use and to produce a power use signal,
- a computer processor adapted to process said power use signal to determine at least two functional states of the master electrical device,
- switch means controlled by the computer processor adapted to connect an electrical supply from the supply electrical outlet to each of the controlled electrical outlets, which of the controlled electrical outlets to be connected to the electrical supply being determined by a determined functional state.
