LED drivers tout 100,000-hour measured lifespans

Mon, 05/07/2012 - 11:50am

Phihong USA has developed a new series of external AC/DC LED drivers that feature extended lifespans of up to 100,000 hours. The new Stonehenge series LED drivers are designed without E-caps, which dry out over time and shorten the operating life of power supplies.  A subset of the broader PDA012X Series, the Stonehenge Series consists of two drivers: the PDA012A-350C-H-R, which is designed for AC inputs of 220-277VAC, and the PDA012B-350C-H-R, which is designed for AC inputs of 100-120VAC.  Both 350 mA constant-current drivers operate at an output voltage range of 10-43VDC, and are appropriate for display lighting and small strings of high-intensity bulbs. The Stonehenge Series is designed to operate in temperatures ranging from -40°C to 50°C at full power and -40°C to 60°C at reduced output power.  Featuring an ingress protection rating of 20, the drivers are rated for dry environments only. Standard features of the Stonehenge Series LED lighting power supplies include over-voltage, over-current, short-circuit, and open-circuit protections, including brownout and brownout recovery. The drivers also meet UL8750 and UL1310 requirements, bear safety approval markings for both UL and CE, and meet the specifications outlined by Energy Star for SSL luminaires, including a power factor correction of greater than 0.9.
