Title: Dual-input redundant power supply

Abstract: A dual-input redundant power supply system includes a first AC source having a hot line and a neutral line, a second AC source having a hot line and a neutral line, a power relay, and an AC to DC converter connected to the first AC source and second AC source via the power relay. When the first AC source works normally, the power relay controls the first AC source to supply power to the AC to DC converter. When the first AC source does not work, the power relay controls the second AC source to supply power to the AC to DC converter.
