How Programmable DC Power Supplies Enable Automated Testing and Remote Control Introduction Manual testing with benchtop power supplies costs time and introduces human error. When you need to run 500 voltage sweeps at 2 A each, or simulate brownout conditions across 48 hours, turning a knob every five minutes is not an option. Programmable DC power supplies solve this by letting you script voltage and current profiles, log results, and control everything over Ethernet, USB, or GPIB. This article walks through how to set up automated testing and remote control using a programmable DC power supply. It covers hardware connections, software configuration, test sequence creation, and data logging. Whether you are validating battery chargers, testing LED drivers, or qualifying automotive electronics, the same principles apply. We focus on practical steps, not theory. The How Programmable DC Power Supplies Enable Automated Testing and Remote Control approach works because modern supplie...

How to Calculate AC DC Power Supply Total Cost of Ownership Over 5 Years Introduction When you're sourcing power equipment for a production line or test lab, the purchase price is just the beginning. A AC DC Power Supply that costs $5,000 upfront might end up costing $15,000 or more over five years once you factor in energy waste, maintenance downtime, and early replacement. Most buyers focus on the initial quote, but the real financial picture is hidden in operating expenses. Traditional procurement approaches compare wattage and voltage specs, then pick the cheapest unit. That works for a one-off purchase, but not for equipment that runs 8-16 hours daily in industrial environments. This tutorial walks you through a five-step framework to calculate the true total cost of ownership (TCO) for any AC DC power supply. You'll learn what data to collect, how to project energy costs, and where hidden expenses lurk. The method applies whether you're buying a single unit for R...
