It supplies a stable 24 VDC output at 2.5 A and is rated as a Class 2/SELV/PELV power source, ensuring compliance with low-voltage safety requirements. Designed exclusively for low-voltage QS electronics, this unit is not approved for use with motorized shades or high-draw window treatments. Its compact DIN-rail form factor, wide operating temperature range, and international approvals make it suitable for globally deployed control systems. Key Features: Universal Input Voltage: Operates from 100–277 VAC at 50/60 Hz for worldwide installations. Regulated 24 VDC Output: Delivers ±1% voltage accuracy for stable QS system operation. 75 Power Draw Units (PDUs): Capable of powering multiple QS devices on a single supply. Class 2 / SELV / PELV Rated: Meets low-voltage safety classifications for controlled-voltage circuits. 2.5 A Output Capacity: Supports up to 75 PDUs without exceeding Class 2 power limits. DIN-Rail Mountable: Installs onto 35 mm DIN rail per EN 60715 for efficient panel integration. Wide Operating Temperature Range: Functions reliably from 32°F to 131°F (0°C to 55°C). Low Heat Emission: Generates a maximum of only 28 BTU/hr for dense panel installations. High-Efficiency Design: Meets U.S. DOE Level VI efficiency performance standards. Indoor Rated Construction: Suitable for conditioned indoor environments with up to 90% non-condensing humidity. The QSPS-DH-1-75 delivers the reliability and precision required for powering Lutron QS low-voltage lighting control networks.
