Cherokee International Touts CAR2512 1U Front End/Rectifier with Ultra-High Efficiency at Light Loads
31 Março 2008 - 10:00AM
Business Wire
Cherokee International (NASDAQ: CHRK), a leading manufacturer of
power supplies, today announced its 2500 watt CAR2512 front end
intended for low profile, 12-volt (V) distributed power
architecture applications, such as high-performance enterprise and
service-provider switches and routers, mid- to high-end servers,
and storage equipment. Packaged in a small, 1U-high footprint and
measuring 1.65 by 4 by 14.88 inches, the CAR2512 hits an ultra-high
power density of 25 watts (W) per cubic inch. The CAR2512 delivers
208 amps (A), supporting 12V bus architectures that power
point-of-load (POL) converters. As a standout feature, the CAR2512
can achieve 90 percent efficiency at just 20 percent of load, with
a peak efficiency of 91.5 percent � enabling it to surpass today�s
application-orientated efficiency standards such as the 80 Plus�
Gold Standard. The small form factor is ideal for space-constrained
applications where system real estate is at a premium. Up to four
units can be mounted side-by-side to deliver 10,000 watts of power
in just 1U height. Protection features on the rectifier include
input over and under voltage, output over voltage, over temperature
and over current. In addition, a microprocessor-based design allows
for automatic fan speed control, which is ideal for optimizing
noise levels of sensitive office-environment applications. This
model is also available with full I2C communications, providing
intelligent monitoring and control of critical parameters.
"Improving data-center efficiency is a key goal for IT, and
Cherokee International has designed the new 12V, 2500 watt CAR2512
front-end with efficiencies up to 91.5 percent and has placed
particular emphasis on light-load conditions where sever
applications truly operate,� said Mike Wagner, vice president of
marketing for Cherokee International. �As an example, we�ve
improved the power efficiency through the use of patent-pending
circuitry and an innovative thermal management approach to allow us
to recover almost 80 percent of the energy normally dissipated on
the secondary side as heat." Pricing and Availability The CAR2512
is priced at $395 in OEM quantities. Samples and low order
quantities are available now. About Cherokee International Cherokee
