Product Features High Output - Output range at typical 625 rpm engine idle meets or exceeds recommended minimum continuous load requirement identified in NFPA 1901. 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) Electromagnetic Interference Suppression meets SAE J1113 specification - EMI suppression to this specification will not cause interference with the vehicle’s properly designed communication equipment. Long Life Bearings - Feature high temperature grease and are heat stabilized for extended service life in hot engine compartments Conformal Coating - Protects regulator and rectifier against damage from vibration and corrosion. High Temperature Insulation and Coating - Increases durability in hot engine compartments, seals out moisture and protects against corrosion. Output Terminal Hardware is Copper and Brass - Highly conductive and corrosion resistant.
