Abstract

An electrical power conditioning apparatus in accordance with the present invention generally includes an electrical input for receiving power from the power source, a surge suppression circuit and a plurality of electrical outlets. A plurality of parallel channels connect the input to at least one of the plurality of outlets. At least one of the plurality of channels includes a filter circuit and a current sensor circuit for measuring the current through the channel. One or more displays are electrically connected to the current measuring to a visual indication of voltage and current measurements.
