Abstract
A smart dual load control device is operable to control the amount of power delivered from an AC power source to a first electrical load and to switch the power delivered from the AC power source to a second electrical load between an on state and an off state, while providing an advanced set of control features and feedback options to an end user. A control circuit is coupled to first and second controllably conductive devices for controlling the amount of power delivered to the first and second electrical loads, respectively. A power supply generates a DC voltage to power the control circuit and is coupled in parallel electrical connection with the first controllably conductive device such that the power supply is operable to draw current through the first electrical load. The second controllably conductive device is operable to provide substantially zero current through the second electrical load when the second electrical load is in the off state.
