LED Drivers 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.

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.
