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.
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 6 Groove Hard
Anodized 6061 Billet Aluminum and hard anodized coating for wear
resistance and durability.
The Denso Small
Case Hairpin OEM alternator is rated at 130 amps with 90 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 80 amps of available
output at hot idle output, and 100 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,
dependability and proven performance in the field.
