<p>A regulating A.C. power controller regulates the selected levels of power to be applied to a plurality of loads by producing a digital signal directly from the A.C. voltage with a pulse duration representative of load power which can be applied as an input to the microprocessor without the need for prior analogue to digital conversion. The load power level is displayed in terms of percentage of power source. Remote control units, such as a computer, can be connected with the power controller to program it for power level settings and warm up time.</p> |
