Abstract

The Electrical Demand Controller is designed to identify and automatically regulate one or more electric loads in such a way that reduced power consumption is achieved with minimal disruption to the consumer. The device may be programmed to make comparisons between any number or combinations of nominated power consuming devices (targets) that at any moment in time may be consuming power in excess of a pre-determined cumulative consumption limit. Should a predetermined consumption limit be exceeded, the Electrical Demand Controller will de-activate nominated power consuming devices (targets) and then re-activate them so as to maintain power consumption within per-deter mined limit, thus enabling switching in any designated order to control consumption to either select appliances that would cause the least inconvenience to the user, or those that would enable more use of appliances whilst still drawing power values below the pre-set maximum demand, as nominated.
