Abstract
La presente invención se refiere a una fuente de energía eléctrica de corriente directa de emergencia, con el estado de emergencia indicado por inversión de polaridad, caracterizada la fuente de enegía porque comprende una fuente de energía eléctrica de corriente directa principal dispuesto con un protector, que provoca que su salida lleve un estado de máxima impedancia en la ausencia de voltaje a través de sus terminales y una fuente de energía eléctrica de corriente directa auxiliar, conectada en paralelo y en oposición con la fuente principal y dispuesta con un limitador de corriente que normalmente se dispara por la corriente adicional que la fuente principal intenta imponerle.
