REDUNDANT SYSTEM AND METHOD FOR PROVIDING POWER TO DEVICES

The present disclosure provides a system and method for providing uninterrupted power to an external device. The system and method include a power supply module coupled to an AC power source and to an external device via a power line, a switching module coupled to the power line, a redundant power supply unit coupled to the AC power source and to the switching module. The switching module is configured to detect an electrical state of the power line and connect the redundant power supply unit to the power line for providing redundant power to the external device based upon the detected electrical state.
