Patent ID: 7233086

Claim:
An electrical power conditioning apparatus electrically connecting a power source to two or more electrical devices, the apparatus comprising: an electrical input capable of receiving power from the power source; a surge suppression circuit; two or more electrical outlets; one or more first channels, each of the one or more first channels electrically connecting the electrical input to at least a first of the two or more electrical outlets; each of the one or more first channels comprising: a two-stage filter; and a current sensor circuit capable of measuring the current through the first channel; one or more second channels, each of the one or more second channels electrically connecting the electrical input to at least a second of the two or more electrical outlets; each of the one or more second channels comprising: a one-stage filter; and a current sensor circuit capable of measuring the current through the second channel; and one or more displays electrically connected to the current sensor circuits of the one or more first and second channels, and capable of providing a visual indication of current measurements from the current sensor circuits of the one or more first and second channels, wherein: in each of the one or more first channels, the current sensor circuit is positioned at an output of the two-stage filter; and in each of the one or more second channels, the current sensor circuit is positioned at an output of the one-stage filter.
