High Output Alternators

Delco Remy® Alternator Series Take High Output Alternators to a New Level
The Delco Remy high output alternator series offers up to 430 Amps of power for vehicles with high electrical loads.  The 28SI™, is rated at 160, 180 and 200 Amps.  The durable brushless 40SI™ available in 240, 275, 300 and 320 and 55SI
™ 430 Amp alternators provide the highest combination of power density and efficiency in the industry today.  High efficiency translates to less engine horsepower requirements, resulting in substantial fuel savings.

The Delco Remy high output alternator series is ideal for a number of applications that carry heavy electrical loads including:

  • School buses
  • Line-haul commercial trucks with anti-idling equipment
  • Emergency vehicles
  • Refuse trucks
  • Utility vehicles
  • Shuttle buses
  • Recreational vehicles

Vehicles like these not using a premium high output alternator experience premature failures.  These failures can be costly and create unexpected downtime.  The Delco Remy high output alternator series solves this problem while at the same time improving the vehicle’s overall fuel savings. 

The Delco Remy high output alternators are the first in the market designed to operate at temperature ratings of 125°/257°F while also featuring Remote Sense technology.  This technology reads the voltage at the battery and signals the alternator to boost its output to compensate for voltage drops.  This helps the battery maintain a full state of charge, which is key in high output applications.
