Abstract:
1. A dimmer control system for controlling power supplied to a load comprising: (a) a master unit connected in a communication control loop in series with one or more remote units, wherein said master and remote units each have a power level display for displaying a current power level supplied by the system to the load, and control unit circuitry to allow two-way communication between the master unit and the remote units of the power level to be supplied to the load; (b) a dimmer load line supplying power to the load, wherein said communication control loop is superimposed in series on the dimmer load line; and (c) said master unit having a power supply circuit provided with a switched power supply in tandem wit a capacitive power supply, wherein the switched power supply is used during LOAD ON conditions in order to avoid heat generation that would be incurred by otherwise using the capacitive power supply, and the capacitive power supply is used during LOAD OFF conditions in order to avoid acoustic noise (bum) in the load.
