2026 Market Trends & Insights

The industrial power supply market is undergoing a structural shift toward high-density and energy-efficient architectures. AccioMaximizemarketresearch

* Pivoting to GaN/SiC: Driven by cooling costs and energy mandates (like Europe's Ecodesign), manufacturers are moving away from legacy silicon (like in the NES series) to Gallium Nitride (GaN). This allows for 20% more power density in the same footprint. Maximizemarketresearch

* AI Data Center Demand: The 1,000W+ segment is growing the fastest, but there is a rising trend in 48V Direct-to-Rack architectures for AI clusters, displacing the traditional 12V standard. MordorintelligenceResearchandmarkets

* Smart Telemetry: Modern PSUs are no longer "passive" boxes; they now embed digital communication (I²C/PMBus) for predictive maintenance, a feature missing in the legacy NES-150 range. Digitimes
