Abstract: A method and system for incorporating electronic signature analysis in a low voltage power supply to centrally monitor current consumption is disclosed. The electrical loads powered by the low voltage power supply can be tested individually via an automatic test routine by measuring and scaling of current through a differential amplifier. The current consumption of each electrical load can be measured by analyzing a “delta” in the current draw of each electrical load's ON and OFF condition. This value can be compared against a stored table of high and low limits for each electrical load. If a load's current is outside the limits, it will be logged for repairs. A current sensing device can be inserted in series with the output(s) of the low voltage power supply, while in test mode, to allow the automatic test routine to run, and then be shorted out for normal operation.

Abstract: A method and system for incorporating electronic signature analysis in a low voltage power supply in order to monitor current centrally. The electrical loads that are powered by the low voltage power supply can be tested individually via an automatic test routine by measuring and scaling of current through a differential amplifier. The current consumption of each electrical load can be measured by analyzing a “delta” in the current draw of each electrical load's ON and OFF condition. This value can be compared against a stored table of high and low limits for each electrical load. If a load's current is found to be outside the limits, it will be logged for an appropriate user to make repairs. A precision resistor (or other current sensing device) can be inserted in series with the output (or outputs) of the low voltage power supply, while in test mode, to allow the automatic test routine to run, and then be shorted out for normal operation.
