A Low-Cost Automated Test Bench for Server Power Supply in Excel VBA

Servers used in various applications perform critical tasks. A key component of a server for its continuous operation is the Power Supply Unit (PSU), which must be dependable at a reasonable cost. PSU testing must be automated to assure high quality and reliability; however, it might be expensive. This study focuses on the design and implementation of bench automation for testing server PSUs using a remarkable automation approach based on Excel VBA, which supports both GPIB and USB interfacing and does not rely on expensive hardware and software automated testing solutions.
