ADVANCED TECHNOLOGY
THE AGE-OLD POWER PROBLEM
N2Power designs and manufactures a
broad range of ultra small, high efficiency
open frame AC-DC and DC-DC power
supplies. N2Power’s unique technology
delivers more power in less space, while
yielding over 30% more efficiency than
other products.
Most switch-mode power supply designs
haven’t changed much over the years.
Lack of innovation has left the systems
engineer with little choice when designing
the latest products. Microprocessors and
associated logic families have increased
function and density and decreased
physical size, but power requirements
have remained unchanged. OEMs using
1U chassis and other space-constrained
packaging constantly strive to increase
the performance of their products,
driving up power demands and heat
loads despite shrinking form factors.
Manufacturers of servers, routers,
switches, telecom gear, RAIDs,
NSUs, LED lighting systems and other
processor-based equipment constantly
pursue smaller, more powerful, and
more efficient power sources for their
products. N2Power’s unique designs
deliver real benefits to OEMs wherever
packaging, heat dissipation and energy
efficiency are key requirements.

TOMORROW’S TECHNOLOGY
DELIVERED TODAY
N2Power has the answer: a patented
technology that can provide over 90%
efficiency in an AC-DC power supply.
Some models take less than 10.4 cubic
inches of space yet deliver a power
density of over 25 watts per cubic inch.
Our smaller, more efficient power supplies
provide the OEM designer with additional
“real estate” for increased functionality,
reduced thermal loads and cooling
requirements, and lower costs. This
means a final product with a real
competitive edge in the market.
22 N2Power’s patented technology provides over
90% efficiency in an AC-DC power supply. The
XL Series power supplies are the smallest, most
efficient open frame supplies on the market.

PATENTED TECHNOLOGY
N2Power’s power supplies use patented,
high-efficiency topology to eliminate
wasted electrical power while state-ofthe-art packaging techniques provide
extremely high volumetric density.
LESS IS MORE
Place your hand above electronic products
and sense the unused energy rising as
heat. Our unique design captures this
energy and puts it to real use. An N2Power
power supply generates less wasted heat,
reduces the need for forced air cooling,
increases reliability, and operates more
economically. Components of the power
supply are reduced in size and the MTBF
is increased.

GRID FRIENDLY
PFC READY
QUALITY DESIGNED IN
Our patented, high-efficiency design
uses more of the supplied AC power. The
high power factor reduces loads on both
generating stations and air conditioning
systems. Some models require no forced
air cooling at all, making them even more
efficient. High efficiency also means
greater reliability for power supplies
and all the other components in the
system. Reducing the load reduces
heat, extending component life.
All N2Power power supplies are Power
Factor Corrected (PFC) to reduce the load
on the power grid and extend the life of
power generation equipment. N2Power’s
products incorporate PFC throughout the
range of available line voltages, both high
line and low line. Careful design and
packaging provide maximum efficiency.
N2Power uses advanced PCB technology
to deliver the highest density and best
performance in the industry. All designs
are HALT tested to assure that they meet
reliability specifications. Our packaging
design incorporates SMT technology to
automate processes, ensure reliability,
and reduce cost. Each power supply
undergoes a complete functional test
and a multi-hour burn-in to insure
that every unit meets our stringent
quality requirements.
