Claim Text:
1. An input line selector system adapted to selectively connect one of a first input power line and a second input power line to a common node, characterized in that said system comprises: a first switch adapted to selectively provide current flow from said first input power line to said node; a second switch adapted to selectively provide current flow from said second input power line to said node; an automatic line selector connected to said first switch and said second switch, said automatic line selector adapted to toggle either of said first switch or said second switch between an operative configuration and an inoperative configuration based on a pre-determined selection logic and depending on voltage level of at least one of said first input power line and said second input power line being greater than a pre-defined under-voltage lockout level; and said automatic line selector comprises a comparator, generating an output voltage, adapted to receive a first sensed voltage indicative of voltage level of said first input power line, a second sensed voltage indicative of voltage level of said first input power line, and a hysteresis voltage for stable operation and prevention of flickering and undesired rapid switching in said output voltage.
