Abstract
Abstract A redundancy power supply apparatus includes conventional regulating amplifiers having the capability of responding to a remote sensing of the condition of the energization of a controlled bus; together with auctioneering diodes to render only one of the regulating amplifiers at a time in control of the energization of the bus. The remote sensing circuits of each of the regulating amplifiers includes a feedback limiting feature which is effective to maintain the stand-by amplifier in an operative state but at a reduced level. Output indicators are connected to the output terminals of each of the regulating amplifiers to indicate the functional condition thereof.
