Voltage Regulation: Maintains steady output voltage (typically within \pm 1.0\%) under varying generator load and temperature conditions.
Under-Speed Protection (UFRO): Protects the generator from damage during engine slowdown or warm-up by lowering output voltage proportionally when speed drops below a pre-set threshold (Under Frequency Roll-Off).
Excitation Control: Regulates excitation current sent to the generator's exciter field winding based on sensing voltage feedback.
