Phihong new adapters comply with Level VI efficiency requirements

Phihong Announces Level VI Energy Efficiency Compliance for More Than 100 of its OEM Power Adapters

Months in advance of when the US Department of Energy’s latest efficiency requirement will go into effect, Phihong releases compliant adapters to help customers achieve conformity 

FREMONT, CA (December 15, 2015) — Phihong, a leading global supplier of OEM power solutions, has announced that more than 100 of its power adapters spanning 2.5–120W and 5–56V are compliant with the US Department of Energy’s (DOE’s) new Level VI energy efficiency requirements, which will go into effect on February 10, 2016 and will impact all OEMs active in the US market.

Designed to conserve power in consumer and industrial products, the new Level VI energy efficiency standard increases active mode efficiency by approximately five percent, and reduces the allowable amount of no-load power consumption to 0.1W from the 0.5W allowed by Level IV efficiency standards. The Level VI standard also expands the range of products it governs to include multiple-voltage external power supplies and products with power levels higher than 250W. Medical power supplies approved by the US Food and Drug Administration (FDA), however, are still exempt.

“Phihong is committed to meeting worldwide regulatory compliance initiatives, and is proud to contribute to global energy efficiency efforts by providing our customers with increasingly efficient products,” said Keith Hopwood, vice president of Phihong. “Meeting the DOE’s new Level VI standards required a fair amount of investment, but our more than 100 compliant adapter products will make a significant impact with regard to global energy conservation, especially due to the new no-load power consumption requirements, and we think that investing in the continued environmental health of our planet delivers excellent ROI.”

The DOE estimates that its new Level VI efficiency standard will reduce emissions by nearly 47 million metric tons of carbon dioxide over the next 30 years, which is equivalent to the annual electricity consumption of 6.5 million homes, and will save consumers up to $3.8 billion in energy costs.
