Power-One Announces the Release of MELCHER Brand HR-Series

The World's First 10:1 Input DC-DC Converter, Up to 300W

ANDOVER, Mass., 2012-09-18 12:00 CEST (GLOBE NEWSWIRE) -- Power-One, Inc.
(Nasdaq:PWER), a leading global manufacturer of renewable energy and
energy-efficient power conversion and management solutions, announces the
release of its revolutionary MELCHER brand HR-Series: The world's first DC-DC
converter with an input voltage range greater than 10:1 and with an impressive
typical efficiency of 94% over the input and load range. The converter delivers
up to 300 Watts of output power with no derating over the entire ambient
temperature range of -40 to 70°C and the drastically reduced losses result in
cooler component temperatures hence resulting in considerably higher
reliability. 

Just one power supply covers all nominal battery voltages from 24V to 120V. The
static input range is 15.4V - 150V with dynamic transient deviations to 12V and
168V for 2 seconds respectively. The HR-Series is complying with EN50155,
EN50121 and all common national and international railway and safety standards
and is packaged in a rugged cassette case for 19" rack or chassis mounting
perfect for harsh, convection cooled environments the traditional MELCHER
style. 

The first models in this ground breaking series provide single 12V or 24V and
dual ±12V output. Future models will expand the offering to cover 12V to 110Vdc
in single and a few dual output configurations. Standard features include
current share, 10ms hold-up time with internal capacitor, reverse polarity
protection, inrush current limitation, over-voltage and programmable
under-voltage lockout, remote on/off, adjustable output voltage, all in all
fully self protecting and fully featured. 

"The HR series raises the bar in its power range by being the first and only
solution with a 10:1 input voltage range," stated Helio Sakaya, VP of Marketing
and Product Management for Power Solutions. "Combining this range with its
stellar performance and ruggedness, the HR series sets a new precedence for
design in and qualification in this industry."
