When it comes to power supplies, efficiency isn't just a technical detail—it's a bottom-line issue. Whether you're designing control panels, maintaining factory systems, or sourcing equipment for industrial projects across Ireland, knowing how to properly measure power supply efficiency can save energy, reduce heat buildup, and extend the lifespan of your equipment.
At Demesne, we often see spec sheets quoted at face value. But here’s the thing: real-world performance rarely matches lab-perfect conditions. This guide breaks down what efficiency really means, how to measure it accurately, and why it matters to our customers across the Irish electrical and industrial sectors.
Manufacturers love quoting high efficiency figures on their datasheets—but let’s be honest, those numbers often come from lab-perfect conditions that don’t match the real-world setups our customers deal with across Ireland. Whether you're an electrical contractor, panel builder, or engineer working in industrial automation, you’ve probably asked: can I trust that 95% figure on the spec sheet?
Here’s the thing: if you care about heat management, system reliability, and energy costs, you need to measure efficiency yourself—and do it the right way.
At Demesne, we work closely with brands like PULS who’ve refined the science of efficiency testing down to the last decimal. This article breaks down the tools, techniques, and environmental factors that actually make a difference when measuring switched-mode power supplies. If you're buying, specifying, or troubleshooting power supplies here in Ireland, this is the practical knowledge that will save you time—and money.
