High Output Alternators & Dual Alternator Systems

APS’s high output alternators and dual alternator systems provide unparalleled, continuous high power that our clients depend on to get the job done. From 12 to 56 volts, APS specializes in high output alternators for armored and security vehicles (including the new Toyota Land Cruiser 300), commercial and fleet vehicles such as coaches and work trucks, and marine vessels for cruising and racing. We also use our alternators in conjunction with alternative, off-grid and advanced energy solutions, such as lithium-ion battery storage systems and custom-built onboard portable DC power generators. We're also now proudly offering lower turn-on RPM alternators (60-, 90-, and 130-amp models), allowing you to charge secondary power banks, even at idle.

NOTE: Due to the complexity of the 48-volt or higher alternator's required system integration, and the potential for mismatched or incorrectly matched products to be used, APS has made the decision to limit the sale of these products to qualified upfitters and other commercial (B2B) clientele at this time.

APS’s high output alternators offer tested, proven durability. With over 2,000 vehicles currently in the field and 18,000 test miles logged at the Nevada Automotive Test Center, our high output alternators withstand the harshest environments to deliver stable, dependable power. Proudly designed and built in the United States, APS’s high output alternators give you the added output needed to energize equipment such as anti-IED jammers, communication systems, satellite equipment, cooling systems, power tools, work-truck systems, and more.

Features and Benefits

Compact and lightweight
Highly efficient
APS’s high output alternators pack more power into a smaller, lighter case. APS alternators can double or triple a vehicle’s OEM output and with a dual alternator solution, we can provide as much as five times more power.
APS alternators are rated as highly efficient, with efficiency of 80 percent or greater, and therefore consume less fuel, costing less to operate and contributing to less engine wear than other options. In addition, American Power Systems, Inc.’s high output alternators self-cool with singular or dual internal fans and high-performance heat sinks, allowing the user to work these units hard without overheating or causing damage to other equipment.
