Power supply derating determines how much output power a unit can safely deliver as temperature, altitude, airflow, and enclosure conditions become more demanding. This guide explains how to read derating curves, avoid common thermal design mistakes, and apply proper cooling, spacing, and installation practices to improve power supply reliability in real-world applications.
LED driver flickering, stuck at full brightness, or only dims part way? It's usually not a defect. See the real cause behind failed dimming, and learn how to match your driver to the load correctly.
Paralleling AC/DC power supplies increases capacity or adds redundancy when a single larger supply is not practical. Learn the three current sharing methods, voltage matching rules, and derating guidelines.
