(Click image for a larger view) | The SD-20 is a high-performance spline-driven alternator that mounts on a standard vacuum pump accessory pad. It may be used either as a primary or a stand-by alternator for a rated output 20 amps @ 2500 alternator RPM.
Constructed of all NEW materials (with absolutely NO "re-manufactured" content), the SD-20 is designed for durable service, with heavy-duty sealed ball-bearings, two cooling fans, a dynamically balanced rotor, and a special "shear section" designed into the drive coupling. The SD-20 is available for both 14 and 28 volt applications. and is externally-regulated. It may be appropriately matched with our LR3c, LS-1A, or SB1B Controllers (depending) on your application and electrical system configurations). Measuring 4.6" wide and 6" deep, and weighing only 5.75lbs., the SD-20 will clear the tachometer cable and oil filter on stock Lycoming engines.
