The global KNX products & system devices market, of which power supplies are a critical sub‑segment, was valued between USD 10.8 billion and USD 25 billion in 2024, with forecasts ranging to USD 27–63 billion by 2033 at a CAGR of 10–11%Specifically, power supply units (PSUs) show strong growth thanks to rising demand for smart and automated building systems. Key growth drivers include stringent energy‑efficiency regulations (e.g., EU’s EPBD, India’s Eco‑Niwas), adoption of green building certifications, and rising retrofit activities in ageing infrastructure
Advancements in KNX technology—such as embedded SoC transceivers, UPS‑ready units, and IoT integration—enhance reliability and expand application reach Innovations like DALI‑KNX lighting control for daylight harvesting and integrated energy‑metering modules fuel adoption in commercial and residential sectors
KNX Power Supply Market Segmentation
1. By Output Capacity
Includes low‑power (1280 mA), and UPS‑integrated PSUs. Low‑power units suit small apartments, mid‑power for larger homes, and high‑power for commercial buildings with dense device networks. UPS variants ensure bus availability during outages—e.g., ABB SU/S series Rising installations mean higher capacity units are gaining share.
2. By Input Voltage Type
Sub‑segments: 230 VAC mains-powered, DC‑input (24–30 VDC), and hybrid models. Most systems use 230 VAC input; DC and hybrid models are emerging to integrate with rack-mounted UPS or solar/battery systems This diversification enables KNX integration in industrial racks and off‑grid setups.
3. By Integration Features
Basic PSUs offer only voltage and choke. Smart units include diagnostics, overcurrent protection, surge suppression, and network telemetry. High-end models embed IoT monitoring, SELV signalling, and configurable alarm outputs. These enhance safety, maintenance, and integration—critical in smart buildings.
4. By Application Type
Segments include residential, commercial, industrial, and retrofit. Residential units focus on compact form‑factors, commercial PSUs support higher loads and redundancy, industrial-grade ones add robustness, and retrofit models are designed for minimal disruption in existing wiring infrastructures, facilitating brownfield upgrades
Emerging Technologies & Product Innovations
KNX PSUs are rapidly evolving to include built‑in communication (Ethernet/IP, KNXnet/IP), enabling remote diagnostics and integration into energy management systems (EMS) and IoT platforms. Semiconductor suppliers now offer turnkey KNX SoCs with integrated power regulation and encryption, reducing BOM and accelerating OEM development . UPS‑ready modules (e.g., ABB SU/S 30.640.2) allow seamless battery support for buses during power interruptions
Collaboration between KNX vendors and IoT/cloud companies is creating solutions for centralized energy dashboards and demand‑response functionalities—often incentivized by utilities with rebates up to 30% Open‑protocol KNX platforms are being bundled with DALI lighting systems, HVAC controls, and energy‑metering devices to deliver unified energy‑management packages.
Product innovation is also evident in form factors and configurability. DIN‑rail PSUs now include diagnostic LEDs, modular stacking, remote reset capabilities, and built‑in choke filters. Some newer units accept DC input (21–30 V), opening possibilities for solar‐hybrid installations Collaborative efforts continue between semiconductor firms, system integrators, and building automation associations to standardize features like cybersecurity, remote firmware updating, and digital twin modeling.
