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.

Technology

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.

Mounting

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 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.
