<p>A regulating A,C. power controller (10) regulates the selected levels of power to be applied to a plurality of loads (1-N) by producing a digital signal directly from the A.C. voltage with a pulse duration (D) representative of load power which can be applied as an input to a microprocessor (44) 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 (32) such as a computer, can be connected with the power controller to program it for power level settings and warm up time.</p> |
