Bosch school bus alternator offers efficiency, long life
Bosch has introduced a new alternator specifically for the school bus market. The alternator incorporates Bosch Self Protection Regulator technology that automatically reduces the output to prevent failure when under-hood temperatures reach 257 degrees, then returns to normal when the temperature drops.
In addition to the Bosch Self Protection Regulator, dual internal cooling fans optimized for air flow help maintain the alternator’s even temperature under all operating conditions.
“This is the ideal alternator for school buses with a lot of stop-and-go driving, long stops at idle and amperage-eating accessories such as chair lifts,” said Fred Padgett, group product manager, Starting and Charging Products for Bosch.
The alternator produces 200 amps operating output and 120 amps at idle. The higher charge rate at idle prolongs battery life by reducing deep cycling.
Additional features include Bosch patented high-efficiency winding technology that uses 30 percent more copper than conventional replacement alternators, producing increased efficiency and fuel savings.
The external regulator and rectifier combine with the alternator’s heat sink design to rapidly dissipate heat, and the rectifier body design prevents clogging from heat-damaging debris. The heat-treated, long-life steel bearings and heat-resistant, water-repelling lubricant also contribute to efficiency and durability. The alternator also features a reduced slip ring diameter to cut down on carbon brush wear.
Bosch’s school bus alternator is backed by a 24-month, 200,000-mile warranty.
