Features 1. Self-Excited Function: The alternator with shunt excitation is self-excited with an R230 automatic voltage regulator. 2. Monitoring of Excitation Current: The regulator monitors the exciter excitation current based on the alternator output voltage. 3. No Sustained Short Circuit: Simple design; alternators with parallel excitation do not support sustained short circuit operation. 4. High-Quality Replacement: The automatic voltage regulator board is designed for precise fit and easy installation. 5. Premium Material: The R230 AVR automatic voltage regulator is constructed from high-grade ABS material for reliable and stable performance.
