Lutron QSN-4A5-S PRO LED+ Phase Adaptive 4-Zone Fixture Controller
The Lutron QSN-4A5-S is a high-performance Energi Savr Node (ESN) designed to provide world-class dimming for a wide variety of lighting loads. Equipped with PRO LED+ technology, this 4-zone surface-mount controller offers "phase-adaptive" dimming, allowing it to operate in either forward-phase or reverse-phase (ELV) modes. This flexibility ensures compatibility with virtually any dimmable LED, CFL, incandescent, or halogen fixture.
Designed for both standalone use and integration into larger Lutron systems like Athena, Quantum, and HomeWorks, the QSN-4A5-S is the ultimate solution for spaces that require precise, low-end dimming without flicker or shimmer. Its surface-mount design allows for easy installation in electrical closets or plenum spaces, making it a favorite for commercial offices, retail environments, and luxury residences.
Key Features
- PRO LED+ Phase Adaptability: Automatically or manually selects between forward-phase and reverse-phase dimming for optimal performance.
