Lutron Energi Savr Node 4-Zone 16A 0-10V Dimming Controller | QSN-4T16-S

Lutron QSN-4T16-S Energi Savr Node 4-Zone 16A 0-10V Controller

The Lutron QSN-4T16-S is a high-performance fixture controller designed to provide centralized dimming and switching for $0-10V$ compatible lighting. Featuring four independent zones, each capable of switching a 16A load, this Energi Savr Node (ESN) is the professional choice for commercial spaces utilizing LED or fluorescent fixtures that require a precise $0-10V$ control signal.

This unit is engineered with Lutron’s patented Softswitch technology, an arcless switching design that prevents relay contact degradation. This ensures a massive 1,000,000-cycle product lifespan, even under the high inrush currents typical of modern LED drivers. With integrated inputs for occupancy and daylight sensors, the QSN-4T16-S makes energy code compliance (such as Title 24 and ASHRAE 90.1) simple and efficient.
