Phihong USA:
PLA UNREGULATED ADAPTERS SECURITY ACT REGULATIONSCOMPLY WITH U.S. ENERGY INDEPENDENCE AND
Tuesday, July 01, 2008

Phihong, the global leader in power solutions, now
offers an extended line of unregulated switching adapters that comply with the U.S. Energy
Independence and Security Act that goes into effect in July. Designated the PLA Series, the
adapters are available in 1W, 2W, 3W, and 5W single output voltage models and meet Level IV
efficiency. The PLA adapters can be used in place of non-compliant unregulated linear adapters,
and are ideal for applications such as wireless communications, cordless headsets, Blue Tooth
device chargers and cell phones.
“Phihong is the only manufacturer offering a complete range of adapters that comply
with the Energy Independence and Security Act, and the only one making linear replacement
adapters available as standard solutions to the general market,” said Keith Hopwood, vice
president of marketing for Phihong USA.
“While the new regulations are forcing manufacturers to design alternatives to the linear
adapters they are currently using, Phihong is doing it in support of our longstanding companywide
green initiative.”
Phihong is also able to offer its PLA Series linear replacement adapters at a lower cost
than traditional switching adapters because they have eliminated the control and feedback
circuits and components. Also, the adapter simply uses one primary control circuit. “The
products have the benefits of a wide-range input switcher but the output regulation is more like a
linear product,” Hopwood said.
The PLA Series devices are available as fixed wall plugs (1W, 2W, 3W, 5W). The PLA
Series adapters feature high efficiency, double insulation have short circuit protection with auto
recovery, are safety approved by UL as limited power sources. The devices have a no-load
power consumption of less than 0.3W, zero minimum load, and meet the minimum efficiency
required by Energy Star and the Energy Independence and Security Act. Unlike linear adapters,
these products have a wide input voltage range of 90VAC to 264VAC.
