    • An appliance is provided with an improved power management system for controlling the total amount of current provided to at least a first load device of the appliance. The power management system is comprised of a microprocessor, an alternating current voltage source, a voltage regulating circuit, a clamping circuit, at least one load device, and a MOC and a triac for each of the at least two load devices. The clamping circuit outputs a fixed voltage of 5.7 volts during the positive portion of the ac cycle and a fixed voltage of −0.7 volts during the negative portion of the ac cycle. The fixed voltages are input to a microprocessor which utilizes these inputs to control the average voltage and the amount of time the current is turned on to each of the at least first and second load devices. A current sensing circuit is used to monitor the current to one of the at least two load devices to provide feedback to the microprocessor so that the microprocessor can adjust the average voltage and current to the at least two load devices so that the total current consumed does not exceed a pre-determined level.
