N2Power Announces the XL280 Ultra-Compact AC-DC Power Supply Family

Industry-Leading Power Density and 90% Efficiency for the OEM Market

SIMI VALLEY, CA--(Marketwire - January 14, 2010) - N2Power, a Qualstar Company (NASDAQ: QBAK), today announced the XL280 Series, a family of very compact, 280 watt AC-DC switching power supplies. Ten models deliver output voltages from 12V to 56V, and up to four units can be wire-OR'ed together to increase the total main output power up to 1,015 watts.

The XL280 Series supplies leverage N2Power's unique "green" packaging technology to deliver more power in less space, while reducing wasted input power and lowering cooling requirements. N2Power's patented design leaves the heat in the load, not in the power supply, reducing power consumption, improving reliability and lowering the cost of ownership.

The XL280 Series delivers 280 watts of output power from just 15.9 square inches of system design real estate. Very low profile packaging yields more than 13 watts per cubic inch power density in less than 1U, making the system designer's job much easier. The XL280 family is designed for OEM applications such as industrial automation, telecommunications, gaming systems, kiosks, security systems, architectural lighting and network servers.

"The XL280 Series gives our OEM customers a distinct packaging benefit, while also reducing overall power consumption and cooling requirements. It delivers greater efficiency and packs more power in a smaller package than any other product on the market," said Randy Johnson, N2Power business unit manager. "Our unique technology gives OEM engineers new flexibility in power system design that pays real competitive dividends in their final products."

The XL280 Series incorporates the same industry leading features as its widely regarded XL125, XL160, XL275 and XL375 power supply families, including active power factor correction for reduced input power, active inrush current protection, active current sharing circuitry and remote on-off. Notably, the XL280 Series allows both 5V standby and 12V auxiliary outputs to be wired Or-able when the main output is disabled. Finally, synchronous rectification delivers exceptionally high efficiency: up to 90% in some models.

N2Power supplies meet a full range of international agency requirements, including RoHS, UL, CE Mark and FCC Class B.

N2Power's XL280 family of power supplies is sold worldwide through its network of representatives and distributors. Sample units are available. Call 805-583-7744 or visit for further information.
