Bosch has launched the new heavy-duty Long Haul Extreme alternator, designed to provide superior power output on the road and at idle, with advanced electronics and design that ensure trouble-free operation, increased battery life, and fuel savings.
Long Haul Extreme alternators come 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. The Long Haul's high charge rate at lower engine rpm prolongs battery life by reducing deep cycling.
Long Haul Extreme features Bosch ‘intelligent’ battery sense technology. If the vehicle into which the alternator is going already has battery sense, connect the vehicle's wiring harness to the proper terminal on the voltage regulator, and the Long Haul is ready to go to work. If the vehicle is not equipped with battery sense, there is no vehicle wiring harness connector to attach to the battery sense terminal, and the Long Haul alternator, with Bosch Intelligent Battery Sense, functions without a vehicle's battery sense. No ‘jumper wire’ must be connected between the battery sense terminal and the B+ terminal of the alternator so the alternator can function properly.
These alternators are equipped with a brush compound that enables the brushes in the Long Haul Extreme to last as long as, or longer than, brushless alternators.
Bosch Long Haul Extreme voltage regulators are built with thermal protection, which allows the alternator to sense extremely high underhood temperatures that could potentially damage internal components of any alternator and cause it to fail prematurely. The temperature-sensing feature of the voltage regulator allows the alternator to continue to operate at a reduced voltage output until the engine compartment reaches normal operating temperature, at which point the voltage output returns to normal.
