350 amp
ALTERNATOR FEATURES
High Output
Output range at typical 625 rpm engine idle meets
or exceeds recommended minimum continuous load
requirement identified in NFPA 1901. Up to 350 amps
available at 14 volts.
High Efficiency
High Efficiency means lower internal alternator operating
temperature, resulting in longer alternator life. Less
engine power needed to produce electric power means
more engine power available for other needs.
Unique Brushless Construction
Elimination of rotating windings, brushes and slip rings
yields durability, extends service life, eliminates arcing
and reduces electromagnetic interference. (EMI)
UPGRADE REPLACEMENT FOR Electromagnetic Interference Suppression meets
C619, N1222 & A1-608 SAE J1113 specification
EMI suppression to this specification will not cause
interference with the vehicle’s properly designed
communication equipment.
