Abstract
An apparatus for error checking in a power supply includes a power module that determines that the power supply is in a self-test condition. The self-test condition involves the power supply being connected to an input power source while it is disconnected from the electronic load that it normally services. A load module connects an internal test load to the power supply when the power supply is in self-test condition, and an error checking module performs error check operations on the power supply while it is connected to the test load. The apparatus also includes a notify module that actuates an indicator when the error checking module determines that there are one or more faults in the power supply. The apparatus may also include a log module for storing error messages and reports in non-volatile memory.
