Feature: 1. For Excitation System: The 2 phase induction automatic voltage regulator is a part of the excitation system of the brushless AC generator, which uses a linear voltage with a slope down to 18Hz. 2. Working Principle: The AVR senses the voltage in the main generator winding and controls the power fed into the exciter stator, thus controlling the main rotor to keep the voltage within the limits. 3. Speed Protection: Continuously monitor the generator shaft speed, and provide under speed protection for the excitation system by linearly reducing the generator output voltage to make it lower than the preset threshold. 4. Accurate Control: Uncontrolled excitation is limited to a safety period through the internal shutdown of AVR output equipment, providing connection for a remote voltage trimmer, allowing users to finely control the generator output. 5. Device Connection: Analog inputs allow connection to power factor controllers or other external devices with compatible outputs, with droop CT connected facilities, allowing parallel operation with other similar generators.
