Brush Generator Automatic Voltage Regulation AVR STL-F-3

Automatic Voltage Regulator Universal AVR STL-F-3 For Brush Generator
STL-F-3 is a half-wave phase controlled thyristor type Automatic Voltage Regulator and forms part of the excitation

system for a brushless generator. In addition to regulating the generator voltage, the AVR circuitry includes under

speed and sensing loss protection to ensure safe, reliable control of the generator. Positive voltage build up from

residual levels is ensured by the use of proficient semiconductors in the power circuitry of the AVR.
