Lutron Energi Savr Node 4-Zone 20A 0-10V Dimming Controller | QSN-4T20-S

Lutron QSN-4T20-S Energi Savr Node 4-Zone 20A 0-10V Controller

The Lutron QSN-4T20-S is a high-capacity fixture controller designed to provide centralized dimming and switching for $0-10V$ compatible lighting. Featuring four independent zones, each capable of switching a full 20A load, this Energi Savr Node (ESN) is the ideal solution for commercial spaces utilizing LED or fluorescent fixtures that require a $0-10V$ control signal.

This controller is engineered for maximum reliability, utilizing Lutron’s patented Softswitch technology to prevent relay contact degradation. This ensures a product lifespan of 1,000,000 cycles, even when handling the high inrush currents typical of modern LED drivers. With integrated inputs for occupancy sensors, daylight sensors, and IR receivers, the QSN-4T20-S facilitates effortless energy code compliance and sophisticated automation.
