The invention comprises an energy dimmer drive and energy pilot that controls the amount of current and voltage conveyed from an input to a load, based on values selected by the user. The current and voltage is varied by controlling the spacing between the primary (5) and secondary (6) winding of a variable transformer (11), as well as the movement of a core (18) in the transformer through a minicomputer, relay cards and/or transistors, sensors and readers. The electric energy power variation is continuous, always rephased according to pre-established values and without microswitches, and is controlled instantaneously.
