Remy International Inc., manufacturer and distributor of Delco Remy heavy-duty starters and alternators, is offering its most powerful and efficient alternator yet. The Delco Remy 55SI has a durable brushless design and is rated at 420 amps at 12 volts and up to 275 amps at 24 volts.
The model is commonly used in the aftermarket on fire and rescue trucks due to its compact design and high output performance at engine idle. The 55SI is available today on new fire truck orders at all original equipment manufacturers.
"The 55SI is the highest output Delco Remy alternator - not to mention the highest output machine in its class," says Eric Bippus, senior vice president, aftermarket sales and marketing. "No other alternator can provide this combination of performance, a brushless design and an efficiency rating of 80% in this frame size."
The company says it is an ideal application for utility and work trucks to power inverters and plug-in power tools, lights and other electrical equipment. One 55SI can replace a dual alternator system, freeing up space under the hood for other accessories. It also supports the electrical load requirements of long haul trucks equipped with multiple battery auxiliary power units.
The 24-volt models rated at 250 and 275 amps meet the high electrical load demand of transit buses, mining equipment and other off-highway vehicles. The 55SI high output alternator is currently standard equipment on wheel loader and grader applications with a major off highway OEMs.
High efficiency alternators translate to less engine horsepower requirements, Remy says, resulting in substantial fuel savings.
