Heavy-Duty Long Haul Extreme Alternator

Bosch has launched the heavy-duty Long Haul Extreme alternator, designed to provide power output on the road and at idle, with advanced electronics and design that ensure trouble-free operation, increased battery life and fuel savings.

• Eliminates need for brushless technology 
• Compact and lightweight design, weighing up to 34% less than brushless alternators
• Features Bosch ‘intelligent’ battery sense technology
• Available in 170- and 200-amp versions, producing respectively 170 and 200 amps at 6,000 alternator rpm operating output, and 120 and 122 amps at 2,000 alternator rpm
• High charge rate at lower engine rpm prolongs battery life by reducing deep cycling 
• Operates under high temperature situations, with dual internal cooling fans optimized for maximum airflow to help maintain even temperature
• Operates at up to 74% efficiency, resulting in fuel savings versus brushless types that operate at 55% efficiency
• Contains circuitry that allows operation/energizing via built in D+ terminal or as a ‘one wire’ alternator as well, with absolutely no modifications
• ‘Brush’ compound enables brushes to last as long as, or longer than, brushless alternators
• Includes thermal protection, which allows the alternator to sense extremely high underhood temperatures
• Temperature-sensing feature of allows continuous operation at a reduced voltage output until engine compartment reaches normal operating temperature below 257 F (125 C)
• Bearing technology provides long life by utilizing steel that has 40% longer life when tested at a 3,000 Newton meter belt load
• Grease has a 30% longer lifetime when tested at 130 amps output
• Bearings run 10 to 15% cooler, operating at less than 120 C when run at 6,000 alternator rpm
