FREMONT, CA May 7, 2012)— Phihong USA, a leading global supplier
of energy efficient and highly reliable power solutions for OEM lighting technology, has developed a new series of external AC/DC LED drivers that boast extended lifespans of up to 100,000 hours. The
Stonehenge series LED drivers are designed without E-caps, which dry out over time and shortenthe 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
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
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. Thesemodels 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. For more
