Product Description
The Large Case Denso Hairpin 270 Amp XP series high output alternator is a component of a next generation high efficiency, severe duty
charging system specifically engineered for DC Power Engineering. This system consists of a 270 Amp alternator and internal regulator.
The alternator produces a maximum of 270 amps and will produce a minimum of 170 amps continually at low idle speeds and maximum
output above 1800 engine RPM. The alternator has a maximum efficiency in excess of 75 percent. The rectifier is mounted onboard the
alternator and consists of 12 50 amp press fit diodes. The brush holder assembly and slip ring are environmentally protected and the
bearings are heavy-duty, oversized premium bearings. The alternator housings are precision-machined cast aluminum and all components
are of OEM quality. All major components being carefully chosen for maximum performance and reliability.

This new charging system features an advanced proprietary stator winding of a new design that maximizes efficiency with near 80 percent
sectional density of the winding coupled with very low coil resistance. This gives the alternator maximum low speed output, as well as a
90% reduction of magnetic pulsation with the stator windings built in cancel circuit to minimize electrical noise. The internal regulator is a
proprietary design advanced multifunction digital regulator that completely integrates into the vehicles PCM through the OEM wiring
harness to retain all vehicle specific functions such as internal temperature compensation, lamp terminal monitoring, load response
control, and alternator load factor.

The Large Case Denso Hairpin 270 Amp XP series alternator is specially designed to mount directly in the OEM mounting location with no
modification. All electrical connections shall be in the original locations. The alternator features a custom machined drive pulley for
increased output at idle speeds and retains OEM belt length. The pulley is 7 Groove Hard Anodized 6061 Billet Aluminum and hard
anodized coating for wear resistance and durability.

The Large Case OEM alternator is rated at 130 amps with 80 amps at idle. The supplied alternator makes 190 amps at normal idle. The
vehicle needs a maximum of 100 amps to supply existing electrical loads with all accessories on leaving little room for additional
accessories. The supplied alternator will supply an additional 90 amps of available output at hot idle output, and 110 amps additional at
cold idle output, and up to 140 amps at highway speeds.

The Large Case Denso Hairpin 270 Amp XP series alternator is manufactured to the highest quality standards in the USA with premium USA
made or sourced components for the highest quality possible. All of our high output alternator's parts are carefully chosen for the
maximum durability
Extreme Performance Through Innovation
DC Power Engineering’s Proprietary XP Series
alternators are built on the world’s first SC (Segment
Conductor) alternator design. The XP series alternators
are 20 percent lighter and provide a 50 percent
increase in output than a conventional wound
alternator. This is achievable by using rectangular
copper for its stator, which increases the density of the
windings from 45 percent to 70 percent. These
patented technological advances have made it possible
to increase the generation efficiency by 10 percent to
improve fuel consumption and performance. The XP
series alternators are capable of producing a minimum
of 150 amps at idle at 200°F and can produce as much
as 200 amps at idle depending on the vehicle
application thus producing as much as 70 percent of it's
maximum output at idle. All of these breakthroughs in
technology have allowed the XP series alternators to be
the most reliable, durable and best performing
alternator on the market
