Patent ID: 8326551

Claim:
A method for incorporating electronic signature analysis in a low voltage power supply, comprising: scaling a current into a voltage signal with a range of 0-20V via said low voltage power supply utilizing at least one differential amplifier electrically in communication with said low voltage power supply; controlling a plurality of input parameters of said low voltage power supply utilizing a said module control board; decoding said plurality of input parameters utilizing a decoder; placing said low voltage power supply in a test mode by setting said plurality of input parameters equal to a predetermined value in order to turn OFF a plurality of field effect transistors (FETs) utilizing said module control board; dividing said voltage signal into signals with a range of 0-5V utilizing said module control board; utilizing said low voltage power supply in said test mode to centrally measure an individual current consumption for each electrical load among a plurality of electrical loads associated with a machine module; providing a predetermined range of high and low current consumption limits for each of said plurality of electrical loads stored as a Non-Volatile Memory (NVM) table; comparing said individual current consumption against said predetermined range of high and low current consumption limits for said electrical load to determine if said current consumption falls outside of said predetermined range of high and low current consumption limits for said electrical load in order to identify at least one electrical load among said plurality of loads requiring a subsequent repair; and inserting a plurality of precision resistors in series with at least one output of said low voltage power supply such that when said plurality of field effect transistors are turned ON said plurality of precision resistors are shorted in order to place the machine module into a normal operation mode.
