Delco Remy Alternator Specifications

One of several major car components manufactured and distributed by Remy International, Delco Remy alternators have been an industry standard for over 90 years. A division of General Motors from 1918 to 1994, Delco Remy alternators are high output and heavy duty vehicle alternators. These alternators are categorized for use and performance, including brushless models.

22SI HP Heavy Duty Alternator

Weighing 14.1 pounds with dimensions of 7.79" H x 8.54" L, the 22SI Heavy Duty Alternator boasts a performance output of 150 Amps/12 Volts as well as a maximum speed of 10,000 RPM continuous and 12,000 RPM intermittent.. The mounting is a SAE J180 standard PAD mount.

23SI Heavy Duty Brushless Alternator

The performance output of the 23SI Heavy Duty Brushless model is slightly lower than that of the 22SI, coming in at 145 Amps/12 Volts. This model is also much heavier than the 22SI at 19.1 lbs, with dimensions of 7.79" H x 9.75" L. However, this model performs at the same maximum speed as the non-brushless model, 10,000 RPM continuous and 12,000 RPM Intermittent. It also uses the same mounting with a SAE J180 standard, PAD mount.

28SI High Output Alternator

Designed to work with vehicles requiring a higher level of electrical output, these alternators are lighter and more fuel efficient. Constructed for use in school buses, truck, utility vehicles, and emergency vehicles, they are available in three different mounting and two Amp options. The 180 Amp option boasts a performance output of 180 Amps/12 Volts when in motion and 125 Amps/12 Volts while engine is in idle. The 200 Amp option has the same engine idle output and a 200 Amp/12 Volt performance output when in motion. The mounting options available are the J180 Hinge (Standard Delco Remy Style), J180 Hinge (Long Leece Neville Style) and the PAD mount. The maximum speed for this model is 10,000 RPM continuous and 12,000 RPM intermittent. Extremely light in comparison to other models, the 28SI High Output is only 8.5 lbs.

50 DN Heavy Duty Transit/Coach Alternators

Specifically formulated for coach and transit applications, the 50 DN is available in gear or belt drive models with corresponding mounts; the belt drive model employs a radius pad mount, while the gear drive model has a flange mount. The performance output of this model is dependent on the model, with the belt drive offering 300 Amps/12 Volts and the gear drive model having a 270 Amps/24 Volts output. The maximum speed of the 50DN model is 6,500 RPM continuous and 7,000 RPM intermittent. The largest alternator model offered by Delco, the 50DN weights 100 lbs. and measures 10.12" H x 17.75" L in the belt drive model and 9.1" H x 16.0" L in the gear drive model.
