Phihong USA has developed a constant-current external LED driver for high-power applications, including street and parking area lighting. The 125 W drivers are available in outputs of 700 mA, 1050 mA, and 1400 mA. Combined with a wide range of operating temperatures, the drivers are ideal for high- power lighting installations in harsh environments.

The 125 W driver series is rated for universal inputs of 100 V_AC, to 304 V_AC, which is ideal for both North American 120 V_AC, to 277 V_AC, and European 230 V_AC, to 240 V_AC mains voltage ranges. The lighting power supplies are water resistant and fully potted, featuring an ingress protection rating of 65. The series also features an extremely wide range of operating temperatures, from -40°C to +60°C, making it ideal for a variety of applications outside of climate-controlled environments.

Bearing cUL/UL and CE compliance approvals, the LED driver series is also energy efficient, featuring typical ratings over 91% at inputs of 120 V_AC and greater than 93% at inputs ranging from 230 V_AC, to 277 V_AC.
