CR724
Alternator regulator for 14V systems
Application & Technical Summary
CR724 regulates the output voltage of a 14 V alternator to a constant value
The regulator continuously senses the alternator’s output voltage, rpm, temperature, excitation current. It adjusts the excitation current to keep the output voltage on a constant level.
