ABSTRACT OF THE DISCLOSURE
Device for decreasing electrical power
consumption in inductive or resistive loads and particularly
for decreasing electrical power consumption in public
lighting systems. Based on the elimination of the sinusoidal
half-wave and on the continuity through the action of a fixed
or variable resistor, the saver overcomes the disadvantages
of present devices, may be used in any type of lamp or
resistive or inductive load, has programmable timing, extends
the lamps, its cost is low, saves power and its size is small.
