Reliability testing of a Low Voltage Power Supply(LVPS) and test station design for the Front-End Electronics of the ATLAS Tile Calorimeter

We present two test-station designs for testing the latest version of a switch-mode power supply for the front-end electronics of the ATLAS hadron TileCal at the LHC. The new test station significantly improves fault detection as well as reliability. We further discuss the steps taken to test the new TileLVPS (Low Voltage Power Supplies), using a Custom based software to perform tests and graphically display and record all performance metrics. The test station verifies performance specifications laid out by ATLAS TileCal and ensures protection against over-temperature, over voltage and over-current. These test stations will build upon the previous generation of testing stations used in the initial production of the TileCal system and will power the next generation of upgraded LVPS hardware.
