AC/DC LED driver for outdoor lighting can power several luminaires
Phihong USA has developed a 72-W constant voltage LED driver designed to power area, wash, and architectural lighting in harsh environments. Designated the PDA072B-24VG, the driver has a Class 2 output of 24VDC at 3A and is compliant with the Energy Star specifications regarding solid-state lighting luminaires. Designed for use with separate driver ICs to power several luminaires from a single source, the PDA072B may be used in a wide range of environments, both damp and dry. The fully potted, water-resistant driver has an ingress protection rating of 65, and is operable in temperatures ranging from -40°C to +60°C. The unit also features power factor correction greater than 0.9, per Energy Star specifications for power supplies in SSL luminaires, and bears safety approval markings from UL and CE. Fully equipped with over-voltage, over-current, short-circuit, and open circuit protections, the 72-W power supply’s minimum average efficiency rating has been measured at 84 power for 120 VAC input and 88 percent for 277 VAC input. It also features a measured lifespan of 50,000 hours at maximum load.
