Product Overview:
The SVR460 Automatic Voltage Regulator is a half-wave phase-controlled thyristor type automatic voltage regulator (AVR), which is part of the excitation system for the brushless AC generator.
In addition to regulating the voltage of the generator, AVR also has a low-speed protection function to ensure safe and reliable control of the generator. The power of excitation is directly supplied by the output terminal of the generator.
The power supply circuit of AVR uses high efficiency semiconductors to obtain the excitation voltage from the remanence.
The AVR is connected to both the main stator winding and the excitation winding and provides closed-loop control accuracy of ±1% for the output voltage.
Apart from obtaining power from the main stator, AVR also obtains sample voltage from the output winding to achieve control over the output. The AVR controls the current output to the excitation system based on the sampled data, and the host controller controls the output voltage within a certain range by compensating for motor load, speed, temperature, and power factor.
The frequency measurement circuit continuously monitors the motor output, and when the generator speed drops below a preset value, low-speed protection is provided by reducing the output voltage proportionally to the speed. The under frequency protection set point can be changed by adjusting the under frequency protection (UFRO) potentiometer. The 50Hz or 60Hz mode can be easily selected by connecting relevant terminals with jumpers.
Connection terminals are provided for remote voltage regulating trimmer, allowing users to achieve precise control of the generator output voltage.
