DAVENPORT, Iowa, Aug. 25, 2025 /PRNewswire/ -- American Power Systems, Inc. (APS) recently launched the Ultra Performance at Idle (UPI) series, its next-generation line of high output alternators that provide more output across the board at both lower and upper RPM. In addition, the increased power output at lower RPM means faster charging capability at lower speeds, including at idle.

Available in 48-, 24-, and 12-volt models, the UPI series offers six different configurations from 165 amps to 390 amps at output for all vehicles APS products serve. This includes the popular Ram ProMaster^® and Ford Transit^®, among other commercial and fleet vehicles including RVs, vans, motorcoaches, buses, shuttles and work trucks of all kinds.

"This is a game-changer in the ever-evolving mobile power market," said APS President & CEO Amy Lank. "Our customers have asked for more power, and we've heard them loud and clear."

As onboard electronics, safety systems, and auxiliary devices have multiplied, the need for more power and charging has increased to meet the needs of modern technology. While the new UPI high-output alternators offer more power at both ends of the RPM spectrum, they can start generating voltage at lower RPM, which translates to quicker battery charging. This early activation reduces the dependency on high RPM for effective charging, making it possible to maintain optimal battery levels even during low-speed operations.

This is especially useful for vehicles in an idling scenario or in city driving where vehicles often run at lower speeds. By generating power earlier, it also helps keep the battery charged more efficiently and reduces the risk of undercharging. Electrical components can work more reliably, improving overall performance and reducing the chances of electrical failures.
