The proposed circuit can be used to alter the speed of one or more celing fans or bulbs up to a maximum power of 1000 watts by changing the volume of power applied from the load itself. The adjustment calibration is incredibly constant and steady on account of an exclusive polarization circuit which lowers the […]
