Phihong LED Drivers Exceed Expectations with 100,000 Hour Measured Lifespans

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 350mA constant-current drivers operate at an output voltage range of 10-43VDC, and are ideal for applications including display lighting and small strings of high-intensity bulbs.

“Solid-state lighting provides greater energy savings and longer operating lifespans than incandescent or fluorescent lighting; however, most manufacturers cannot provide OEMs with power supplies that can match LEDs’ longevity,” said Keith Hopwood, vice president of marketing for Phihong USA. “The new Stonehenge series, which boasts measured life spans of 100,000 hours, resolves this issue by meeting LED operation benchmarks, cutting energy costs, and lengthening the average amount of time between installation and maintenance or replacement services.”

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. Additionally, Stonehenge Series drivers come with an extended eight-year warranty, and their small, lightweight design enables easy integration into a variety of indoor and architectural design projects.

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.

The other constant-current LED power supplies in the PDA012X Series possess the same standard features as the Stonehenge Series models, but with lifespans of 50,000 hours. These models are available at a lower cost and come with a standard three-year warranty.

All LED drivers in the PDA012X series, which includes the two Stonehenge Series models, measure 132mm x 30mm x 22mm and weigh 150 grams. Pricing for the Stonehenge series models, designated PDA012X-350C-H-R, start at $68.61 in single unit quantities.

Phihong will be exhibiting at the Lightfair International trade show and conference May 9-11, 2012 at the Las Vegas Convention Center in Las Vegas, Nevada. Please visit us at booth #3945 for more information about these products and the rest of our lighting power technology portfolio.
