Delco-Remy 21Si & 22Si Type Alternators
for Extreme Duty Use
150, 170, 200 and 250 AMPERAGE MAX OUTPUT DUAL RECTIFIER
ALTERNATOR
The Quick Start™
EXTREME DUTY DUAL RECTIFIER ALTERNATOR™
Alternators produce AC current, just like
the current from your house wall outlet. Then it uses a bridge rectifier,
typically with 6 diodes, to convert the AC current to DC to send to the
battery. With OUR 100% NEW Extreme Duty Dual Rectifier Alternator , you get 12 Diodes,
which spreads the current load over a much larger area making the
alternator twice as durable and twice as efficient at converting the AC
current to DC power for the vehicle. The many benefits include: less heat build
up, less current loss, higher amperage output when hot, more power at
idle. Plus, the
service duty and life increases substantially. When the rectifier heats
up the diodes won't pass as much amperage through them, therefore, the
amperage output drops. With our double rectifier alternator you have
twice the amperage carrying capacity and double the cooling surface area
to keep the diodes cool. This all adds up to......
MORE POWER, LESS HEAT PROBLEMS and GREATER RELIABILITY.
Note: The 21 & 22 Si series
alternator does not come with pulley
Remember, Our Dual Rectifier
Alternators are 100% New so you don't pay a core charge. You also get to keep your old alternator. Contact us if your not sure of your application.
A great choice for
installation on non-GM vehicles and other conversions.
