School buses present a unique set of challenges.  A school bus performs the majority of its workday at slow speeds. At the same time, lighting and equipment associated with safety and passenger mobility add electrical loads that must be met at these same slow speeds.  Delco Remy High Output Alternators are specially designed to contend with the demanding electrical loads of school bus operating routines.  Add to that the durable brushless design, high temperature ratings and proven technologies like Remote Sense and you've got alternators in a class by themselves.
