Phihong has developed a new constant-current external LED driver for high-power applications, including street and parking area lighting. Designated the PDA125 series, the 125 W drivers are available in outputs of 700 mA, 1050 mA and 1400 mA. This versatility, combined with a wide range of operating temperatures, makes the drivers suitable for high-power lighting installations in harsh environments.
Offering optional 0–10 V dimming, the PDA125 series meets all ENERGY STAR requirements governing power supplies in solid-state lighting luminaires. It is rated for universal inputs of 100 to 304 V a.c., which is suitable for both North American 120 or 277 V a.c. and European 230 to 240 V a.c. mains voltage ranges.
The lighting power supplies are water resistant and fully potted, featuring an ingress protection rating of 65. The series also features a wide range of operating temperatures, from -40°C to +60°C, making it ideal for a variety of applications outside of climate-controlled environments.
The driver series is available in two variations: the PDA125W, which features standard 0–10 V dimming, and the PDA125B, which does not feature a dimming option. Additional standard features for all models include over-current, over-voltage, short circuit and open circuit protections, as well as brownout recovery and power factor correction of greater than 0,9.
