An electrical power supply device includes a DC-DC power convertor receiving an input voltage and producing a first output voltage or a second output voltage that is less than the first output voltage, the first and second output voltage each less than the input voltage and a device controller in communication with the DC-DC power convertor. The device controller has one or more processors and memory. The memory includes instructions which causes the device controller to command the DC-DC power convertor to output the first output voltage when the input voltage is equal to or greater than a threshold voltage and which causes the device controller to command the DC-DC power convertor to output the second output voltage when the input voltage is less than the threshold voltage. A method of operating the electrical power supply device is also presented.
