Abstract

An arrangement is disclosed for controlling the power applied to two remote loads energized from a common ac line. An example is a circuit for controlling fan speed and lamp brightness, both loads being installed in a common ceiling fixture, and requiring only a two conductor interconnection to a wall mounted control circuit. An exemplary control circuit employs two conventional controllers, each having a bidirectional, semiconductor switch, (e.g., a triac) having a manually adjustable conduction duty cycle for power control. The control circuit includes shunt and series diodes for mutual isolation of the controllers and for allocating one controller to one load and the other controller to the other load. The arrangement simplifies installation costs in requiring only a two conductor control connection, and is economic in its selection of components for the control function.
