If fast idle charging is important to you, view our ARCO Zeus 24V 7kW High Amperage Alternator here.
NOTE: Arco LTO alternators engage at ~1072 RPM. Most vehicles idle at or below 900RPM. For this reason, it is generally recommended to install a high idle kit if installing an LTO alternator.

If Optimal Charging at Low Speed is Important to You, This is the Perfect Alternator for You.
24V Advantage – Low Turn On (LTO)
The ARCO Zeus 24v 4kW LTO alternator turns on at lower RPMs, runs cooler and provides more power than older designs that are larger and heavier. This alternator continuously generates over 1.4kW (51 Amps) at just under 1,500 RPM, and almost 2.4kW (87 Amps) at 2,000 Alternator RPM. Put in real world terms, a marine diesel engine idling at 750 RPM with a 2:1 pulley ratio is generating over 1.5kW (55 Amps), and a Mercedes Sprinter at 750 RPM with a 3.21:1 ratio is generating over 2.5kW (91 Amps)!
