120W Professional Dimming Power Supply for LED Systems
This versatile driver delivers regulated constant-voltage output at 12V, 24V, 36V, or 48V, selectable to matc120W LED driver with 12V/24V/36V/48V output, PWM or voltage reduction, Triac/ELV/MLV/phase-cut dimming. NEMA 3R outdoor rated, UL/cUL/CE, US design patent.h your specific LED configuration. Power factor correction operates at high efficiency, minimizing reactive power draw and ensuring grid-friendly performance across commercial and residential installations.
Users configure either PWM or voltage-reduction signaling at the output stage, accommodating both digital and analog LED control requirements without hardware swaps. Dimming integration spans the full spectrum of installed infrastructure—Triac wall controls, electronic low-voltage transformers, magnetic low-voltage systems, and standard phase-cut dimmers—ensuring backward compatibility with existing lighting schemes.
The NEMA 3R-rated enclosure withstands outdoor precipitation and temperature cycling without auxiliary protection, while its US design patent-certified construction distinguishes authentic units from imitations. UL, cUL, and CE markings satisfy inspector requirements across North American and European project sites.
