The 40W Constant Power NFC Programmable Driver delivers versatile, high-efficiency performance for professional lighting applications, applied mainly to street lights, tunnel lights, and industrial lights where IP20-rated internal mounting suits fixtures already rated IP>54, and compatible with both Class I and Class II luminaires. This DEXAL 40W stands out for its automated dimming intelligence — a five-level timer function with astronomical and time-interval modes lets fixtures adjust light output on a schedule without external controllers; output current itself stays easily adjustable via NFC programming for quick on-site configuration, and the driver carries DALI-2 and D4i certification along with full-range protection against surge, over-voltage, and short-circuit conditions, with wattage and dimming profile open to OEM/ODM customization for project-specific deployments.
