The Lutron QSPS-DH-1-75 is a compact, DIN-rail-mounted power supply designed specifically for Lutron QS-Link systems. It provides reliable 24-volt DC power to low-voltage QS devices such as keypads, sensors, and interfaces within a lighting or automation control network. Engineered for both residential and commercial installations, it ensures stable power delivery and helps maintain proper communication across the QS-Link.
This power supply delivers up to 75 Power Draw Units (PDUs), which allows it to support a substantial number of QS devices depending on the total load of the system. Its universal 100–277 V AC input makes it suitable for a wide range of electrical environments, while the regulated 24 V DC output ensures consistent performance. Because it mounts on a standard 35 mm DIN rail, it fits neatly into control panels and structured wiring enclosures, keeping installations organized and professional.
The QSPS-DH-1-75 is intended for low-voltage control components only and is not designed to power high-demand devices such as motorized shades or other heavy loads. Built with safety and energy efficiency in mind, it meets Class 2, SELV/PELV, and international certification standards. Its durable construction and compact size make it a practical and dependable power source for any Lutron QS-based system.
