Power-One, Inc.: Press release

CAMARILLO, Calif., 2011-04-28 23:28 CEST (GLOBE NEWSWIRE) --
Power-One, Inc. (Nasdaq:PWER), a leading global manufacturer of renewable
energy and high-efficiency power conversion and management solutions, announces
the availability of its new XPGe12.48 1200W rectifier for the Aspiro™ network
power systems series. The XPGe12.48 raises the bar for high efficiency in
medium-size rectifiers, by providing efficiency exceeding 95% across a wide
load range. 

To accompany the new rectifier, Power-One is also releasing the iPWER Aspiro
Front Access platform, combining high efficiency with user-friendly front
access in a compact 2U (19"/ETSI) format.  The new Aspiro platform supports up
to four XPGe units and 4.8kW of power output, while offering flexible DC
distribution capability derived from its pluggable circuit breakers and system
controller.   The Aspiro Front Access management functions, coupled with the
XPGe's high efficiency and 21.8 W/in3 of power density, facilitate the
reduction of operating costs and carbon footprints in space-critical
applications, through significant decreases in energy, cooling and site
management expenses. 

"The release of the iPWER XPGe12.48 not only complements our Network Power
portfolio with high-efficiency rectifiers in the low-power range, but also
paves the way for deploying hybrid solutions in low-power applications like
pico cells and microwaves," Cemil Tolun, Vice President of Network Power
Systems noted recently. "The new Aspiro platform is compatible with our Hybrid
controller, which together with XPGe12 will deliver the optimum cyclic
performance in unstable-grid and off-grid telecom sites." 

The XPGe12.48 rectifier is full-featured, with a wide input operating voltage
range, a 46 to 57 VDC output voltage range and 1200W of output power.  This
device is also fully-protected, including EN 61000-3-2 harmonics, EN 61000-4-5
surge immunity, plus EN 61000-6-2, EN 61000-6-3 and EN 61000-4 EMC safeguards. 

The iPWER Aspiro Front Access platform provides state-of-the-art system control
with Web-based management functionality and Simple Network Management Protocol
(SNMP) via its PowCom™ software, plus sophisticated features supporting
extended battery life and remote monitoring of critical site equipment, such as
HVAC and generators. This platform's rugged design ensures reliable operation
even when grid-level power quality is unstable.
