Feature: 1. [Main Feature] AVR senses the voltage in the winding of the main AC generator and controls excitation to maintain the output voltage of the AC generator within the specified limit range, compensating for the load speed, temperature, and power factor of the AC generator. 2. [Safety Design] The internal shutdown of the AVR output device limits the maximum excitation to a safe period. This situation remains locked until the AC generator has stopped. 3. [Overvoltage Protection] Automatic voltage regulator includes an overvoltage protection function, ensuring safe use of the AC generator. 4. [Multi Function] Provide a connection for a remote voltage regulator, allowing users to finely control the output of the AC generator. Provide an analog input that allows connection to a rate factor controller or other external devices with compatible outputs. 5. [Underspeed Protection] Provide underspeed protection for the excitation system by reducing the output voltage of the AC generator proportionally to the speed below the pre set threshold.
