Features:_x000D_1. It is a half-wave phase-controlled thyristor-type automatic voltage AVR and is part of the excitation system for a non-excited generator._x000D_2. In addition to regulating the generator voltage, the AVR circuit also includes low speed and inductive loss protection. The excitation power comes directly from the generator terminals._x000D_3. By using an efficient semiconductor in the power supply circuit of the AVR, it is ensured that a positive voltage is established by the residual horizontal voltage._x000D_4. It sealed electronic device stabilizes the output voltage of the brushless generator by adjusting the generator excitation current_x000D_5. Temperature operation freely: the original manufacturing excellent glass glaze can be in the high temperature environment above 200 degrees_x000D_6. Quickly corresponding rapid build pressure: 1.8s speed built pressure recovery time less than or equal to 2s low frequency led indicator_x000D_7. High reliability and stable quality: high precision, small drift, good stability, fireproof and soft rubber_x000D_8.
