Alternators

12 & 24V ALTERNATORS

  • 12V 130A SAE J180 mount
  • 12v 130A Pad mount
  • 24v 95A SAE J180 mount
  • 24v 95A Pad mount
  • 2 or 3 terminal

The brushless alternator is used mainly in large trucks and large agriculture and construction equipment.
Because these vehicles are used for long periods of time in harsh environments, the brushless alternator must have higher reliability and longer life than alternators used in regular passenger cars. DENSO brushless alternator is both durable and reliable due to the elimination of brushes and slip rings.

Benefits and Features:

  • 80A at Engine Idle (12V)
  • Tested to endure heat producing engines
  • Long-life brushless design
  • Heavy-duty front and rear bearings
  • Corrosion resistant rectifier and rotor
  • Heat resistant windings
  • Non-soldered connections for easier service
  • Compact and lightweight design
  • One wire connection
  • Load dump protection
  • SAE J180 mount/ Pad mount
  • Warranty: 3 years / 500,000Kms* (On-Road applications)
    *1 year / 2000 hours of operation for mining, agricultural and industrial applications
