ABSTRACT:
An apparatus, system, and method are disclosed for event, time, and failure state recording in a power supply. Disclosed is a power supply that receives AC voltage as an input and provides regulated DC voltage as an output; a microcontroller integrated into the power supply that regulates output voltage and monitors, records, and reports operating conditions of the power supply; and a non-volatile solid-state storage that can be repeatedly read from, written to, and erased by the microcontroller and integrated within the microcontroller such that only a single address is needed to access both the microcontroller and the solid-state storage, the solid-state storage configured to store operating data received from the microcontroller, the operating data including the recorded operating conditions of the power supply.
